Inquiry On A Bash Script Using Sed And Grep -c

Hi all,
I've knowledge about timestamp and i'm trying to use it in a particular scenario. I've multiple folders inside which are different files. Now I'm trying to copy one file (say xyz) which is present in all the folders but has variation in it's content and time of creation into a let's say foldernew.
I'm trying to do this by copying the file xyz from each folders with the new name xyz_(it's orginal timestamp) into folder new.
Can this be done with a single command or do what should I write in a script to execute this?

Note: I want to add the timestamp of xyz when it is created not of the time of copy.

Ok yes this is a homework assignment BUT I am NOT looking to have the answers given to me. I am in the 6th week of my first Linux class ever and we are in our few weeks of beginning scripting. I have some ideas of what to do or where to start but not many and no one to bounce any ideas off...we are using UNIX Bash shell so any others I have no clue. The scenario is that I need a script that searches all my users home directories for bad words. I need the script to report to the screen certain info like username and word found and path. It should ask a user if it is good or bad and if bad be put into a file of list of bad file names, if good remove from list and no longer flagged by the script. What I have so far is wanting to somehow do a loop. I do know that if I do a grep -r -e kill -e steal /home/* I get a list of what I need. I also know that the list is separated by delimiters which I can pipe to get a variable for the things I need. I also know that I can put it to a file with a > filename.txt

What I have no clue is how to start a loop that would do this...

for each line in filename.txt
UNAME=...
LOC=...
TXT=...
echo "Username: $UNAME, Line with bad word found: $TXT, and Path and file name: $LOC. Is this a BAD file? (Y)"
Read YORN

if ["$YORN" = "Y" ]; then
>> (line of text from grep) badfiles.txt
fi

Next or whatever goes there...sorry if this is crazy I just really need some direction. I am trying to learn so please don't give me the answer...that will do nothing for me and I will not be able to explain the code I came up with.

This is my script and the syntax to run this script is give ip and next will be the file or script you want to perform on remote server



#!/bin/bash

# The private key used to identify this machine
IDENTITY_KEY=/home/adnew.pem

syntax()
{
echo "Syntax: Ec2.sh server_ip scriptFile]"
echo "For example: ./Ec2.sh server_ip scriptFile"
exit 1
}

if [ $# -ne 2 ]
then
echo not enough arguments
syntax
fi


echo "Running script $2 on $1"
ssh -ttq -i $IDENTITY_KEY ec2-user@$1 sudo -i 'bash -s' < $2
exit
exit
echo "Done"



on script file i have give for testing

touch /root/test
ls /root/test
exit
exit

it makes the file but do not show the ls output by giving error


tcgetattr: Inappropriate ioctl for device

exit


what I have to do ??

Hello,
I'm working on a shell script that needs to read the a file (file1) a batch (read 2000 lines at a time) and then write those lines to seperate file which I'm using to run ldapmodify command. I need to check some other file size and once this file less than 200kb, i would need to run second batch and so on until file1 is empty.
Quote:
#!/bin/bash
set -x
filesize=200
server=10.11.xxx.xx
filename=fileimport.txt
taofile1=687686.txt
taofile=/var/opt/$taofile1

stty -echo
echo -n "Enter password: "
read passwd
stty echo
context="cn=user1,ou=org1,ou=org2,o=org"
if [[ -s "$filename" ]];then
for lines in $filename
do
head -99997 fileimport.txt >> ldapreadd.ldif && sed -i '1,+99996d' fileimport.txt
if [ -s ldapreadd.ldif ];then
ldapmodify -h $server -p 389 -D $context -w $passwd -v -x -f ldapreadd.ldif &> /dev/null
echo "LDIF script is running. Please wait..."
sleep 60
if [ -f "$taofile" ];then
taofilesize=`stat -c %s ${taofile}`
# if [ "$taofilesize" -ge 200 ];then
while [ `stat -c %s ${taofile}` -ge 200 ]
do
echo " Driver is processing LDIF file. Please wait..."
sleep 60
done
fi
rm -rf ldapreadd.ldif
fi
done
else
echo "$filename file is empty. Exiting script..."
exit
fi

I have 2 issues here. first one script is not reading exact lines as specified. Some times its reading more lines some times less lines. Second issues once it run the first batch, script is exiting. Please advise.

I need to compare a value with different fixed value. Below is the code concept I implemented in my bash script but its giving me error.
Here "a' is the nameserver value that I extract using command line from /etc/resolv.conf. I did not put command here.

#! /bin/bash
a=1.2.3.4

if [ $a == 1.2.3.4 || 5.6.7.8 || 8.9.1.4]
then
echo " You have correct ntpserver"
else
echo"wrong ntpserver"

fi

Am I comparing the value correctly or any suggestion?

Thank you

Hi All,

Im trying to create a script which checks the creation time of a file and if it is more than ten minutes, send out an alert.

For ex : Creation date of file is 10:30 AM
current time is 10:45 AM

Then send an alert/ message.

This is the script i wrote below :

Code:

#!/bin/ksh

filename="/apps/log/file.txt"

if [ -f "${filename}" ]
then
        createTime=`ls -lad "${filename}" | awk '{print $8}'`
        echo "$createTime"
        currentTime=`date '+%M'`
        echo "$currentTime"
        DIFF=$(( $currentTime - $createTime )) 
        echo "$DIFF"

else

        exit 1

fi

I am getting syntax error on the subraction when i try to run this script . I can understand that creation time and current time is in different format thats y this error throws, but i dont know how to rectify it .

I need to find out if the file creation time is more than ten minutes.

Please help me in achieving this output.

I have a bash script executing on an AIX server to a windows share directory to update a windows text file. Most of the file is edited as expected but I have 3 issues that I am not sure how to resolve.

1. Windows text file contains a double backslash (\\) and the \\ is being written back as a single \ which corrupts the file.
2. I am not getting the last line of text in the file written back out.
3. Some lines of text are not written back out completely.

Here is a snippet of my bash script:
cp $Directory/Somefile $Directory/Somefile.$(date +'%Y%m%d')
cat /dev/null > ${HOME}/temp.out

while read -r inpLine; do
patternFound=n
echo ${inpLine} | grep -q 'SOMEPATTERN='
if [ $? = 0 ]; then
patternFound=y
echo "##${inpLine}" >> ${HOME}/temp.out
echo "SOMEPATTERN=newValue" >> ${HOME}/temp.out
fi

if [ ${patternFound} = "n" ]; then
echo ${inpLine} >> ${HOME}/temp.out
fi

done < $Directory/Somefile
mv ${HOME}/temp.out $Directory/Somefile

I am have a bash script like this:

#!/bin/bash
while true;
do
(printf %s "$(date '+%A %W %Y %X')"; echo -n ", " ; printf %s "$(ps -eo pcpu,pmem,comm | grep statsd)") >> tope.txt;
sleep 2;
done

What I want is the output of this command be entered into tope.txt like this:

Friday 20 2015 11:28:21, 0.0 0.4 /usr/libexec/systemstatsd

but what I get is output like this in multiline. :

Friday 20 2015 11:28:21
,
0.0 0.4 /usr/libexec/systemstatsd

What can I do to fix this?

Hi All,

I have two scripts, the aim of these two scripts is, to check whether a particular script is running or not, if it wont runs, then throw a mail.

How i Achieved this output is, I wrote first script.

I created an infinite while loop which performs below steps

1. It creates a touch file
2. Triggers the script which needs to be monitored if its working or not.
3. Removes the touch file.

If the second step fails, then the remove file command will not happen and the script will stuck there itself.

I created an another script which checks the creation time of the touch file and if it is more than ten minutes, it means the second step in the first script is hanged, which also means that particular script is not working.

So if the creation time is more than 2 minutes the second script will throw a mail.

Below are the two scripts.

Code:

#!/bin/ksh



userid="chansd"

filename="/apps/log/check.txt"

while true ;do
touch $filename
pass=`/apps/eDMZ/call_st.ksh $userid`
sleep 20
rm $filename
done

Below script checks the file creation time and throws email if it is older than 2 minutes
Code:

#!/bin/ksh


filename="/apps/log/check.txt"

if [ -f "${filename}" ]
then
if test "`find $filename -mmin +2`"
then
echo "script is not working ! Please act on it" | mail -s "Script  is not working" Example@mail.com
fi


else

        exit 1

fi

What im going to do is

1. I am going to run the first script in background so it runs forever.
2. I am going to run the second script in cron forevry 5 mins to check the file creation time.

3. So if the first script hangs . I will kill the process using process id and after the issue resolves with the inner script, I will run the main script again.

I am new to Linux, Please let me know if this approach will work as expected.

Hi guys,

i'm beginner with Unix, I tried my best, but I Really don't know how to finish it .

here's my problem : I have to do something like Student system - student's name | subjects | mark |credits.

after starting script it will ask you for Student's name, then which subject, then the mark will appear.

It's a homework, and I have my own idea how to solve it, but cannot finish it, i don't want complete solution, just a help!

Code:

#!/bin/bash
echo "Students name"
echo -n "Enter student's name: "
read name
echo
case $name in
Example1|Math) echo "C" ;;
Example2|Programming) echo "D" ;;
Example3|WWW) echo "A" ;;
Example4|Economie) echo "-" ;;
esac

I don't now how to bring together case with second things which is "enter subject".

I appreciate any help
