Remove a line from a file using sed (useful for updating known SSH server keys when they change)

When you SSH to a server who's hostname or IP has changed since the last time a connection was recorded in the known_hosts file a warning will be displayed since this indicated a possible DNS spoofing attack. If this is a known change then this command will remove the previous entry and allow the SSH connection. The SSH client will prompt you as if it was the first time connected to the server. Replace ${LINE} with the line of the offending key in ~known_hosts. 49 in the sample output. Show Sample Output

sed -i '${LINE}d' ~/.ssh/known_host

Returns the absolute path to a command, using which if needed

This works in multiple unixes, not only linux, for different paths. On solaris, if you do not have which, you can use: ksh whence -p anypath/a_command.sh | sed "s|^./|$(pwd)|" ksh whence -p Show Sample Output

list with full path

Use the -a flag to display all files, including hidden files. If you just want to display regular files, use a -1 (yes, that is the number one). Got this by RTFM and adding some sed magic. [bbbco@bbbco-dt ~]$ ls -a | sed "s#^#${PWD}/#" /home/bbbco/. /home/bbbco/.. /home/bbbco/2011-09-01-00-33-02.073-VirtualBox-2934.log /home/bbbco/2011-09-10-09-49-57.004-VirtualBox-2716.log /home/bbbco/.adobe /home/bbbco/.bash_history /home/bbbco/.bash_logout /home/bbbco/.bash_profile /home/bbbco/.bashrc ...

List only directories, one per line

Normally, if you just want to see directories you'd use brianmuckian's command 'ls -d *\', but I ran into problems trying to use that command in my script because there are often multiple directories per line. If you need to script something with directories and want to guarantee that there is only one entry per line, this is the fastest way i know Show Sample Output

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.

Find out how old a web page is

I used to use the Firefox "View page info" feature a lot to determine how stale the web page I was looking at was. Now that I use mostly Chrome I miss that feature, so here is a command line alternative using wget. The -S says to display the server response, the --spider says to not download any files/pages, just fetch the header. The output goes to stderr, so to grep it you use 2>&1 to combine the stderr stream with stdout, the pipe that to grep for Last-Modified. You can use curl instead if you have it installed, like this: $ curl --head -s http://osswin.sourceforge.net | grep Mod

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

Install pip with Proxy

Installs pip packages defining a proxy

Get names of files in /dev, a USB device is attached to

This command lists the names of your USB devices connected and what file in /dev they are using. It's pretty useful if you don't have an automount option in your desktop or you don't have any graphical enviroment.

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"

Look at your data as a greymap image.

Keep width to a power of 2 to see patterns emerge. 512 is good. So is 4096 for huge maps. PNM headers are super basic. http://netpbm.sourceforge.net/doc/pbm.html

Push your present working directory to a stack that you can pop later

If are a Bash user and you are in a directory and need to go else where for a while but don't want to lose where you were, use pushd instead of cd. cd /home/complicated/path/.I/dont/want/to/forget pushd /tmp cd thing/in/tmp popd (returns you to /home/complicated/path/.I/dont/want/to/forget)

List upgrade-able packages on Ubuntu

Taken from apticron and modified.

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Cleanup debian/ubuntu package configurations

Sometimes, simpler is better.
