User: f241vc15
Functions: find grep sed

Look for a string in one of your codes, excluding the files with svn and ~ (temp/back up files). This can be useful when you're looking for a particular string in one of your source codes for example, inside a directory which is under version control (e.g. svn), removing all the annoying files with ~ (tilde) from the search. you can even change the command after -exec to delete (rm) or view (cat) files found by 'find' for example

cat /var/log/secure | grep smtp | awk '{print $9}' | cut -f2 -d= | sort | uniq -c | sort -n | tail
2009-03-30 15:49:54
User: empulse
Functions: awk cat cut grep sort uniq

Searches /var/log/secure for smtp connections then lists these by number of connections made and hosts.

cat /var/log/secure | grep sshd | grep Failed | sed 's/invalid//' | sed 's/user//' | awk '{print $11}' | sort | uniq -c | sort -n
2009-03-30 15:48:24
User: empulse
Functions: awk cat grep sed sort sshd uniq

Searches the /var/log/secure log file for Failed and/or invalid user log in attempts.

svn rm `svn status | grep "\!" | cut -c 8-`

Functions: cut grep rm
Tags: svn

If (when) you forget to "svn rm" files from your repository, use this to let your repository know you want those files gone. Of course this works with adding and reverting too.

< /path/to/file.txt grep foo
2009-03-29 02:43:40
User: atoponce
Functions: grep

Several times, I find myself hitting my up arrow, and changing the search term. Unfortunately, I find myself wasting too much time typing:

grep kernel /var/log/messages

Redirecting STDIN allows me to put the search term at the end so I less cursor movement to change what I'm searching for:

< /var/log/messages grep kernel

If you're using the emacs keyboard binding, then after you press your up arrow, press CTRL+w to erase the word.

If this has already been submitted, I couldn't find it with the search utility.

This command will replace all instances of 'foo' with 'bar' in all files in the current working directory and any sub-directories.

Allows you to save progress without committing.

To revert to an undo point, svn revert then apply the undo point with patch.

svn revert -R . && patch -p0 < .undo/2009-03-27_08:08:11rev57

grep '' -m X file1 > file2

User: sardanapalos
Functions: grep

It extracts X number of lines from file1 and dumps them to file2.Using grep with the empty string '' extracts the complete lines (i.e. no filtering takes place) and the -m flag indicates how many lines to extract out from the given file. Then using the redirect > operator we send the extracted lines to a new file.

User: psytek
Functions: cut echo grep ls read tr

This command will grep the entire directory looking for any files containing the list of files. This is useful for cleaning out your project of old static files that are no longer in use. Also ignores .svn directories for accurate counts. Replace 'static/images/' with the directory containing the files you want to search for.
