Feb 15, 2011

I have a requirement to find the files having its name as ack_reply. However, there are many other files in the same directory as these resides. Now I have to remove these files from the folder and retain others after 7 days. So I tried to write the below script with grep command.

General :: Can't Quit Terminal Command - Grep Some_word?

Sep 5, 2010

After typing "grep some_word" on terminal 6, the system doesn't do a thing, just lets me type endlessly. I've tried "Esc", "q" , [CTRL] + x, "exit" and no luck. I bet I'll kick my ass when you tell me but at the moment I can't figure it out. Rebooting would probably solve the problem but there must be a better way.

General :: Break Copy Process When Folder Size Reaches Its Maximum?

Mar 19, 2011

I have written a script.

#/bin/bash
a=`du -sh /root/samplefolder | cut -f1`
echo $a > testfile

[code]....

The aim of this script is, when the folder reaches 20M then attributes will be set to that particular folder so that no newfiles and folders cannot be created or copied to that samplefolder. whenever i copy a file morethan 20M to that folder its getting copied fully and then the attributes were applied. But i dont want this to happen, when the folder reaches its maximum current write operation to that folder should be stopped automatically with a error.
