Not as far off as you thought, now is it?

works on all unices.

If you still connect to your wireless access point manually and need to use wpa_supplicant, the above fu will grep all of the known SSID from your wpa_supplicant.conf file, present it in a Zenity list and return the SSID name you choose. I've wrapped this command in to a bash script that then up's the interface, associates and autenticates. Saves me from using NetworkManager ;)

Based on the MrMerry one, just add some visuals to differentiate files and directories

Next time you see a mac fanboy bragging about 64-bitness of 10.6 give him this so he might sh?

Compile *.c files with "gcc -Wall" in actual directory, using as output file the file name without extension.

Debian: Mark all dependent packages as manually installed. So they are not automatically removed if you remove some meta package - like gnome-desktop-environment for example.

Do this with caution.

This allows the output to be sorted from largest to smallest in human readable format.

This command will find the biggest files recursively under a certain directory, no matter if they are too many. If you try the regular commands ("find -type f -exec ls -laSr {} +" or "find -type f -print0 | xargs -0 ls -laSr") the sorting won't be correct because of command line arguments limit.

This command won't use command line arguments to sort the files and will display the sorted list correctly.

It never ends

Using DynDNS or a similar service not only allows access to your home machine from outside without needing to know what IP the ISP has assigned to it but it also comes in handy if you want to know your external IP address. The only purpose of the sed command is to remove the leading "host.na.me has address " part from the output. If you don't need to discard it you can simply use

Gets the internal and external IP addresses of all your interfaces, or the ones given as arguments

The same as the other user, but smarter, using -d and -f

This one will work a little better, the regular expressions it is not 100% accurate for XML parsing but it will suffice any XML valid document for sure.

Calculates md5 sum of files. sort (required for uniq to work). uniq based on only the hash. use cut ro remove the hash from the result.
