If you want to relocate a package on your own, or you just want to know what those PREIN/UN and POSTIN/UN scripts will do, this will dump out all that detail simply. You may want to expand the egrep out other verbose flags like CHANGELOGTEXT etc, as your needs require. It isn't clear, but the formatting around $tag is important: %{$tag} just prints out the first line, while [%{$tag }] iterates thru multi-line output, joining the lines with a space (yes, there's a space between the g and } characters. To break it out for all newlines, use [%{$tag\n}] but the output will be long. This is aside from rpm2cpio | cpio -ivd to extract the package files.

Get a list of all the unique hostnames from the apache configuration files. Handy to see what sites are running on a server.

I created this command to give me a quick overview of how many file types a directory, and all its subdirectories, contains. It works based off file extension, rather than file(1)'s magic output, because it ended up being more accurate and less confusing. Files that don't have an ext (README) are generally not important for me to want to count, but you're free to customize this fit your needs. Show Sample Output

If you have lots of subversion working copies in one directory and want to see in which repositories they are stored, this will do the trick. Can be convenient if you need to move to a new subversion server. Show Sample Output

Quicker way to search man pages of command for key word Show Sample Output

searches through the linux dictionary for the word you're trying to spell (you can use regular expressions, e.g. "< /usr/share/dict/words egrep bro[c]+o[l]+i" ) Show Sample Output

Useful for grepping an IP range from the maillog. When for instance dealing with a spam-run from a specific IP range, or when errors occur from or to a specific IP-range. In the example above the IP range 183.0.0.0/10 (183.0.0.0 - 183.63.255.255) To grep the IP range 124.217.224.0/19 (124.217.224.0 - 124.217.255.255) from the maillog: egrep '124\.217\.2(2[4-9]|[34][0-9]|5[0-5])' -J /var/log/maillog* NOTE: the location of the maillog may vary based upon operating system and distribution.

Just a few minor changes. First the usage of lynx instead of curl so no sed is needed to revert the spaces. Then the usages of egrep instead of grep -e to save a few characters and last the removal of the extra 0. Show Sample Output

Apply to almost linux distroes. Show Sample Output

scrot, curl, egrep, sed, xsel, libnotify-bin must be installed. P.S. Sorry for so long command Show Sample Output

Where COMMAND is the process(es) name. I prefer to get all states but you may add ESTABLISHED in the grep regex. lsof -c apache2 | egrep -o 'TCP.*ESTABLISHED.*$' -nP flags are optional and UDP is irrelevant for established connections Similar but using the process id: lsof -nP -p PID | egrep -o '(TCP|UDP).*$' Show Sample Output

Similar to command 7822, but handles errors gracefully. Show Sample Output

This version builds on my command 8776 (Find the package a command belongs to on debian-based distros). So if you use that command to find package name then you could alternatively use following for package summary: function summpkg { dpkg -s $(whichpkg $1 | awk -F: '{print $1}'); } Show Sample Output

If you make a mess (like I did) and you removed all the executable permissions of a directory (or you set executable permissions to everything) this can help. It supports spaces and other special characters in the file paths, but it will work only in bash, GNU find and GNU egrep. You can complement it with these two commands: 1. add executable permission to directories: find . type d -print0 | xargs -0 chmod +x 2. and remove to files: find . type d -print0 | xargs -0 chmod -x Or, in the same loop: while IFS= read -r -u3 -d $'\0' file; do case $(file "$file" | cut -f 2- -d :) in :*executable*|*ELF*|*directory*) chmod +x "$file" ;; *) chmod -x "$file" ;; esac || break done 3< <(find . -print0) Ideas stolen from Greg's wiki: http://mywiki.wooledge.org/BashFAQ/020

Just use your system preinstalled file Show Sample Output

Provides a cleaner output plus some more details about the IP address. Also, a flaw was corrected where the URL provided the results in Spanish by default. Show Sample Output

The other 2 commands that are listed will also kill the egrep process and any libexec processes because the .exe isn't escaped so it is really using . meaning anything containing exe. The command i posted escapes the (dot) in .exe and then filters the actual egrep process so that it doesn't get killed before the other processes being killed. Also added the -9 switch for kill to send sigterm to the processes, in case people are wondering why processes aren't getting killed after running just kill . This should work better for people :)

I can't find the lid command on my system, there is also another complied program: http://xyne.archlinux.ca/projects/lsgrp/

the find -printf "%f\n" prints just the file name from the given path. This means directory paths which contain extensions will not be considered. Show Sample Output
