Add Tags To Enclose A String

Afternoon forumer's

Im trying to have a if statement perform a check to throw out a string that contains alphanumeric

so anything like ^*&(*"

ive been racking my brain with if statements and checks like

if [ $string = "\^|\*" ]
then
echo "string contains incorrect characters"
fi

however i cant figure it :\

I have a database , there are some table in it , in this database , there is a string "error" , I would like to change it to "warning" , except export all data to text , find and replace string , and then import back to database , is there other method may bulk update the string ? thanks

Hi, I'm trying to use awk to parse multiple strings from a fw log file

I need awk to parse for the following structu 3 IPs in an OR sequence AND string1 AND string2 (IP or IP or IP) && string1 && string2

I'm unable to craft a command that looks for IP 1, 2, or 3 and string 1 or string 2. Below is some of the syntax structure I've tried so far but to no avail. I believe the OR statement is incorrect as the AND arguments appear to be working

cat file |awk /IP/ || /IP/ || /IP/ && /string1/ && /string2/

Hi All,

Using grep command with a defined string, you will get the row. Can I get the column instead of row? For example,

the file content is as below:

AA BB
123 456
789 ABE

execute 'grep ABE file' will give you "789 ABE". Is there any way to get the column:
BB
456
ABE
?

Thank you very much.

Hi,

Right now on my system i have 5/6 users in my /etc/passwd file but all of them are in clear.
I know that normally encrypted passwords are in /etc/shadow and i know that the commands cryptpw and mkpasswd can be used to encrypt a string of character.

If for example an user is like this in passwd :

banana:lasagna:3:0:food:/:/bin/sh

Do i have to edit manually the shadow file with the encrypted string corresponding to "lasagna" here ? And what must i write in this shadow file ?

Thank you for the future answers !

HI all,
I'm writing a perl script to automate VM UUID transformation into a format used by our ServiceNow CMDB/discovery.

Anyone know which perl module to include to use the string length function?

Alternately, how would I determine which perl modules exist that are available to include, vs. which functions each module contains?

thanks in advance,

I compiled the hello world program as my prof instructed.
then I used C+c C+c, delete 'make -k' and replaced with 'g++ -o proj0 -std=c++11 proj0.cc', choose to save the file, and it goes 'compilation exited abnormally with code 1'

note that I do all these by making SSH connection with computer in lab with a linux system

FYI, the whole thing is:

Hello Friends,

I want to pass string variable with its value taken by user as command parameter in shell script, example below:-

echo "Enter New Password:="
read password


perl -pi -e
's/PASSWORD=.*?,/$password,/' abc.txt

Please let me know...
Thanks In advanced.

Hello,
I' ve already install the ns-2.29.
But when i want to execute nam.
I have this error :nam:
[code omitted because of length]
: no event type or button # or keysym
while executing
"bind Listbox <MouseWheel> {
%W yview scroll [expr {- (%D / 120) * 4}] units
}"
invoked from within
"if {[string equal [tk windowingsystem] "classic"]
|| [string equal [tk windowingsystem] "aqua"]} {
bind Listbox <MouseWheel> {
%W yview scroll [expr {..."


How can i install it?

I need to execute this .bashrc string:

alias lml='grep '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}' mail.log | grep "relay=" | awk '{print $8}'' #list mail log

I have tried enclosing the string in alias as lml="..." and alias lml=`...` to no avail. The problem is apparently with the grep "relay=" in that it has to be enclosed in "", as well as the awk that has to be enclosed in ''.

Any ideas on how to get this setup? Thanks.
