  • Change the APP variable's value to whatever you want to install. Depending on how fast your machine is, you'll want to adjust the value 50 to something else. You might also want to play a different game than Gnometris - just make sure it's a GUI game.

  • 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

  • In this case, linux- is the prefix; simply running apt-cache pkgnames would list every package APT knows about. The default APT config assumes -g, --generate; to use the cache as/is, you could similarly run: apt-cache --no-generate pkgnames [prefix] Adding --all-names, like so: apt-cache --no-generate --all-names pkgnames [prefix] would print all the packages APT knows about, using the cache as/is, including virtual packages and missing dependencies. This command was shamelessly stolen from the apt-cache(8) man-page. Show Sample Output

  • If, for example, you want to remove all kernels and headers but the last three versions, you can't use one of that magic all-in-one "remove old stuff" commands. With this simple but elegant command you can remove a range of versions, or a list of versions with e.g. {14,16,20}. Show Sample Output

Rsync remote data as root using sudo
If your user has sudo on the remote box, you can rsync data as root without needing to login as root. This is very helpful if the remote box does not allow root to login over SSH (which is a common security restriction).

a shell function to print a ruler the width of the terminal window.

LIST FILENAMES OF FILES CREATED TODAY IN CURRENT DIRECTORY
Then pipe to 'xargs ls' for a familiar listing, possibly using find's -print0 and xarg's -0 options.

Bingo-like raffle
Random choose numbers from 1 to 100 with 5 seconds interval without duplicates.

return external ip
curl inet-ip.info -> 113.33.232.62\n curl inet-ip.info/ip -> 113.33.232.62 curl inet-ip.info/json -> JSON print curl inet-ip.info/json/indent -> JSON pretty print curl inet-ip.info/yaml -> YAML format curl inet-ip.info/toml -> TOML format http://inet-ip.info

Unaccent an entire directory tree with files.
This command changes all filename and directories within a directory tree to unaccented ones. I had to do this to 'sanitize' some samba-exported trees. The reason it works might seem a little difficult to see at first - it first reverses-sort by pathname length, then it renames only the basename of the path. This way it'll always go in the right order to rename everything. Some notes: 1. You'll have to have the 'unaccent' command. On Ubuntu, just aptitude install unaccent. 2. In this case, the encoding of the tree was UTF-8 - but you might be using another one, just adjust the command to your encoding. 3. The program might spit a few harmless errors saying the files are the same - not to fear.

Combines an arbitrary number of transparent png files into one file
This one liner; combines all sequentially numbered files; in this example IMG_0001.png to IMG_1121.png by generating the shell script, making the shell script executable and then running the shell script to combine the 1121 png into a single png file named _final.png tested on Mac OS X 10.6.3 with ImageMagick 6.5.8-0 2009-11-22 Q16 http://www.imagemagick.org
