kill all foo process

Kill all processes with foo in them. Similar to pkill but more complete and also works when there is no pkill command. Works on almost every Linux/Unix platform I have tried.

Search for an active process without catching the search-process

This does the same thing as many of the 'grep' based alternatives but allows a more finite control over the output. For example if you only wanted the process ID you could change the command: ps -ef | awk '/mingetty/ && !/awk/ {print $2}' If you wanted to kill the returned PID's: ps -ef | awk '/mingetty/ && !/awk/ {print $2}' | xargs -i kill {} Show Sample Output
This is sample output - yours may be different.
```
$ ps -ef | awk '/mingetty/ && !/awk/ {print}'

ptree equivalent in HP-UX

By setting the UNIX95 variable in HP-UX the XPG4 mode is activated, you get new options for ps and other commands, for me the best way to use this is to create an alias named ptree in root profile: alias ptree='UNIX95=1 ps -eH'

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Get the size of all the directories in current directory (Sorted Human Readable)

as per eightmillion's comment. Simply economical :)

convert filenames in current directory to lowercase

The simplest way I know.

List top 20 IP from which TCP connection is in SYN_RECV state

List top 20 IP from which TCP connection is in SYN_RECV state. Useful on web servers to detect a syn flood attack. Replace SYN_ with ESTA to find established connections

Short one line while loop that outputs parameterized content from one file to another

The above is an example of grabbing only the first column. You can define the start and end points specifically by chacater position using the following command: $ while read l; do echo ${l:10:40}; done < three-column-list.txt > column-c10-c40.txt Of course, it doesn't have to be a column, or extraction, it can be replacement $ while read l; do echo ${l/foo/bar}; done < list-with-foo.txt > list-with-bar.txt Read more about parameter expansion here: http://wiki.bash-hackers.org/syntax/pe Think of this as an alternative to awk or sed for file operations

ionice limits process I/O, to keep it from swamping the system (Linux)

This command is somewhat similar to 'nice', but constrains I/O usage rather than CPU usage. In particular, the '-c3' flag tells the OS to only allow the process to do I/O when nothing else is pending. This dramatically increases the responsiveness of the rest of the system if the process is doing heavy I/O. There's also a '-p' flag, to set the priority of an already-running process.

execute your commands hiding secret bits from history records

$ wget --user=username --password="$password" http://example.org/ Instead of hiding commands entirely from history, I prefer to use "read" to put the password into a variable, and then use that variable in the commands instead of the password. Without the "-e" and "-s" it should work in any bourne-type shell, but the -s is what makes sure the password doesn't get echoed to the screen at all. (-e makes editing work a bit better)

Change mysql prompt to be more verbose

You can put this into your shell sourced file like .bashrc or .zshrc to have a different mysql prompt. See http://dev.mysql.com/doc/refman/5.1/de/mysql-commands.html for more informations. Beware that currently with mysql 5.5 the seconds are buggy and won't be displayed if you put this into a .cnf file. With the enironment variable this will work.

In-Place search/replace with datestamped backup

Does an in situ search-replace but leaves a datestamped backup. A variation with more precision: sed -i.`date +%Y%m%d%H%M%S 's/pattern/replace' [filename]

Multiple variable assignments from command output in BASH

This version uses read instead of eval.

Copy the full path of a file to the clipboard (requires xclip or similar)

Handy for those times you need to paste a file path in an IDE or some other app. sudo apt-get install xclip Then, for convenience, alias xclip to 'xclip -selection c' so you can just do something like realpath . | xclip
