Check if the Debian package was used since its installation/upgrade.

This script compares the modification date of /var/lib/dpkg/info/${package}.list and all the files mentioned there. It could be wrong on noatime partitions. Here is non-oneliner: #!/bin/sh package=$1; list=/var/lib/dpkg/info/${package}.list; inst=$(stat "$list" -c %X); cat $list | ( while read file; do if [ -f "$file" ]; then acc=$(stat "$file" -c %X); if [ $inst -lt $acc ]; then echo used $file exit 0 fi; fi; done exit 1 ) Show Sample Output

rename files according to date created

The command renames all files in a certain directory. Renaming them to their date of creation using EXIF. If you're working with JPG that contains EXIF data (ie. from digital camera), then you can use following to get the creation date instead of stat. * Since not every file has exif data, we want to check that dst is valid before doing the rest of commands. * The output from exif has a space, which is a PITA for filenames. Use sed to replace with '-'. * Note that I use 'echo' before the mv to test out my scripts. When you're confident that it's doing the right thing, then you can remove the 'echo'... you don't want to end up like the guy that got all the files blown away.

Add date stamp to filenames of photos by Sony Xperia camera app

Sony's Xperia camera app creates files without time-stamped names. Thus, after deleting files on the phone, the same names will be reused. When uploading the photos to a cloud storage, this means that files will be overwritten. Running this command after every sync of uploaded photos with the computer prevents this. 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.

Set your profile so that you resume or start a screen session on login

From screen's manpage: "Attach here and now. In detail this means: If a session is running, then reattach. If necessary detach and logout remotely first. If it was not running create it and notify the user. This is the author's favorite." Toss this in your ~/.bash_profile so that you never have that "oh crap" moment where you wanted to run something in screen and didn't.

Rapidly invoke an editor to write a long, complex, or tricky command

Next time you are using your shell, try typing ctrl-x e (that is holding control key press x and then e). The shell will take what you've written on the command line thus far and paste it into the editor specified by $EDITOR. Then you can edit at leisure using all the powerful macros and commands of vi, emacs, nano, or whatever.

Random unsigned integer

works at least in bash. returns integer in range 0-32767. range is not as good, but for lots of cases it's good enough.

Set a Reminder for yourself via the notification system

This will be seen through your system's visual notification system, notify-osd, notification-daemon, etc. --- sleep accepts s,m,h,d and floats (date; sleep .25m; date) --- notify-send (-t is in milliseconds && -u low / normal / critical) man notify-send for more information --- notification-daemon can use b/i/u/a HTML

Remote backups with tar over ssh

Execute it from the source host, where the source files you wish backup resides. With the minus '-' the tar command deliver the compressed output to the standar output and, trough over the ssh session to the remote host. On the other hand the backup host will be receive the stream and read it from the standar input sending it to the /path/to/backup/backupfile.tar.bz2

Rename files in batch

Run a command when a file is changed

show git commit history

Find usb device in realtime

Using this command you can track a moment when usb device was attached.

Clone IDE Hard Disk

This command clone the first partition of the primary master IDE drive to the second partition of the primary slave IDE drive (!!! back up all data before trying anything like this !!!)
