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.

Exclude inserting a table from a sql import

Starting with a large MySQL dump file (*.sql) remove any lines that have inserts for the specified table. Sometimes one or two tables are very large and uneeded, eg. log tables. To exclude multiple tables you can get fancy with sed, or just run the command again on subsequently generated files.

find duplicate messages in a Maildir

# find assumes email files start with a number 1-9 # sed joins the lines starting with " " to the previous line # gawk print the received and from lines # sort according to the second field (received+from) # uniq print the duplicated filename # a message is viewed as duplicate if it is received at the same time as another message, and from the same person. The command was intended to be run under cron. If run in a terminal, mutt can be used: mutt -e "push otD~=xq" -f $folder

Calculate md5 sums for every file in a directory tree

E-mail a traditional Berkeley mbox to another recipient as individual e-mails.

Swap a file or dir with quick resotre

This lets you replace a file or directory and quickly revert if something goes wrong. For example, the current version of a website's files are in public_html. Put a new version of the site in public_html~ and execute the command. The names are swapped. If anything goes wrong, execute it again (up arrow or !!).

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

List all Windows services on the command line

On Windows 2000 or later, this command will give a listing of all the registered Windows services. You can then know what the name of a command is in order to start and stop it. e.g. $ sc start Apache2.2 or $ net start Apache2.2 Please note that sc will allow the SERVICE_NAME only, while net will allow both SERVICE_NAME and DISPLAY_NAME. Note that the space between the = and the next word are important. Not very unixy, that. http://www.ss64.com/nt/sc.html http://www.ss64.com/nt/net_service.html http://technet.microsoft.com/en-us/library/bb490995.aspx

Re-use the previous command output

The $(!!) will expand to the previous command output (by re-running the command), which becomes the parameter of the new command newcommand.
