Best Practices To Get One Linux Command To Do Something Else Afterwards?

I've been using this a lot:

find <directory to start search at> -name "<files to search in>" -type f | xargs grep "<string to search for>"

e.g.

find /usr/include -name "*.h" -type f | xargs grep "#define UINT"

now what if I wanted to output the results to a file?

I'm sorry to ask such a simple question but every time I think I figure something out or think I'm going somewhere get stopped dead in my tracks. My friend installed linux on my computer and then moved away immediately so I have no one to help me!

I downloaded the webcam program Cheese. I found through some tutorials that I have to copy the folder to the /opt/ folder and the only way to do that is through the terminal. I found this tutorial and still can't manage to copy the folder. These are the problems I run into:

1. I don't know where to open the terminal. I've tried opening it from the extracted Cheese folder in my downloads folder and from the /opt/ folder itself. It opens up but:
2. when I type the command sudo cp -r cheese /opt/ it will ask for modernnewspeak's password. When I try to type this in nothing happens, even though it JUST let me type in the command. I pressed "enter" thinking maybe it was hiding my password and I get the message "cannot stat 'cheese'. No such file or directory"

please tell me what I'm doing wrong! I tried to follow that tutorial and look through the FAQ here but I cannot figure this out. Thank you in advance!

What I did in windows was create images of my drive and restore them.

in linux I am running

Code:

rsync -aAXv --exclude={"/home/*","/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} /* /path/to/backup/folder

and this creates a folder for me with all my files, and apparently saves meta data like permissions and paths...

Since I'm using arch and things break sometimes,I'm booted into a CLI with errors and cannot figure my way out since I'm a noob... would I be able to just delete my entire root and replace it with the rsync backup without a problem?

Hi,
I made some little applications with qt creator and i wanted to run them on an embedded linux board (linux 2.6.24). To transfer the files i use a SD card. If i move the applications to "/bin" after having mounted the SD card and then "chmod a+x" them then i have no problem running them.
But if i mount the SD card and try to run the applications directly in the folder where i mount it i have an error : "Permission denied". Also when using the command "ls" i notice that if i keep the files in the mounting folder and try to "chmod a+x" them, the modification don't happen. They stay "greyed" and don't go "green". (I don't know if this color code is a standart for linux terminal but maybe this could help you understand the problem).
When mounting the SD card i use the command :
Code:

mount -t vfat /dev/mmcblk0p1 /mnt/SD

So the files are located in /mnt/SD.

Am i missing something or is it not possible to run something like that ?

EDIT :
I tried "mount -t vfat -o umask=0000 /dev/mmcblk0p1 /mnt/SD" to chnage how i am mounting the SD card.

Still "Permission Denied".

With "ls -l" i can see that the permissions are staying :
-rw-rw-rw-

Even if i try something like "chmod 777".

It seems to be a problem related to the fact that the sd card is formated as fat32 but it must stay like that.

Hello,

I studied the command ls for more than 3 hours and I want to do in linux the following commands

1) cd \
2) dir *.exe /s

This browse my entire disk and displays all the executables.
Also I want to see the attributes, the subdirectory, the filename, the file length and the date of creation.

Can somebody help me to make a bashfile with the correct ls switches ?
It should be someting like
cd root
ls -1 -? -?

Thank you very much.

Hi

When i run this command manually on Centos 6.6 it works:

Code:

/usr/bin/find /backup/ -type d -mtime +1 -print0 | xargs -0 rm -rf

but as a cron job it doesn't as i can see a folder with files there from Mar 28:

Code:

55 5 * * * /usr/bin/find /backup/ -type d -mtime +1 -print0 | xargs -0 rm -rf

And here are the logs from cron that it is executing this at the correct time :

Code:

Mar 30 05:55:01 server CROND[9526]: (root) CMD (/usr/bin/find /backup/ -type d -mtime +1 -print0 | xargs -0 rm -rf)

Any ideas why?

Thanks

I installed Linux Mint on my Dell Latitude D630 Wi Fi and I love it!! While the lap top was wired to the internet, I could do anything I wanted to do.

But I have wifi. And, the steps I found online did not help me get wifi set up.

When I type "iwconfig" from the command line, it says "no wireless extensions"

Please help. I need this.

I'm in the need of building a script to clean up my media library. I've been PVR'ing for years now and it's time to clean things up. For example, my TV Shows are saved as such:

/media/storage/Show Name/Season 1/Show Name - S01E01 - Episode Name.mp4

Over the years I've created a bunch of subdirectories further than that and I want to go through and clean those out. For example, the following directory might exist:

/media/storage/Show Name/Season 1/subtitles

If I use the find command, with -type d and -maxdepth 4, I have discovered that the subdirectory I want to delete is in the 4th level. There should be nothing valid in the 4th level and okay to delete.

I don't really know where to start. I tried using the find command with -mindepth 4 but that doesn't seem to work as I would expect. Basically, I want to scan through the library, then I want to test to make sure that the directory isn't "Season XX" and if it is a subdirectory within Season X then I would like to delete that subdirectory.

Any ideas how I can accomplish this?

FYI: I'm using Korrora 21 with BASH.

Hello,

I am trying to install OCI8. I'm pretty sure the last thing I need to do is run the "./configure" command, but no matter where I try to run it, it gives me back a "file not found" or "command not found" error. I have tried this on CentOS and Fedora and always install PHP with yum. I have done many GUI searches looking through the file system for "php" and have tried to run ./configure in every php folder I can find but the command never runs. Any suggestions are very much appreciated. Thanks so much!

-Matt

P.S. Do I even need to do this if I already edited the "php.ini" file and installed OCI8 with PECL? Thanks!

In Linux Mint, I have right clicked on a folder and selected
"Sharing Options" -> checked the boxes to "Allow others to create and delete files in this folder" and "Guest Access..."

When I access the shared folder on Windows 7 it asks for a password. If I type a password in, it works.

I would like to configure it to not ask for a password, but just open the share.
