bnd-ips.txt is a list of IP adresses that is concenated for use as regular expression. Yes, this is still very speedy ;=)
Especially useful with a command line podcatcher like Mashpodder.
Move efficiently between directories.
.
This command adds a couple of extra features to cd, without affecting normal use.
CDPATH use is also unaffected. It introduces and environment variable CDDIR which is used as an alternate home directory.
.
Note: I don't want to alter $HOME because then all my dot files will move.
.
Examples:
.
cd dir
Change directory to "dir" (using CDPATH if necessary)
.
cd dir/file.txt
Change directory to "dir" (containing folder of "file.txt")
This allows you to cut'n'paste, or use
.
CDDIR is unset
cd
Change directory to $HOME
.
CDDIR=/home/flatcap/work
cd
Change directory to /home/flatcap/work
.
For convenience, put the command, and the following, in your .bashrc or .bash_profile
export CDDIR="/home/flatcap/work"
alias cdd="CDDIR=$(pwd)"
Use Curl to upload documents from your linux servers to MS Sharepoint servers.
the -h option of du and sort (on appropriate distrib) makes output "Human" readable and still sorted by "reversed size" (sort -rh)

Maybe there's an easier way to set a timeout in the ssh options...
The other commands were good, but they included packages that were installed and then removed.
This command only shows packages that are currently installed, sorts smallest to largest, and formats the sizes to be human readable.
Prints line numbers making it easier to see long lines that wrap in your terminal and extra line breaks at the end of a file.
:set nu
works too.
Using a GUI file managers you can merge directories (cut and paste). This command roughly does the same (it doesn't ask for confirmation (no problem for me) and it doesn't clean up the empty SRC directories (no problem, trivial).
probably does the same:
cp -l SRC TARGET; rm -rf SRC
Change your Desktop background/wallpaper with feh lightweight command.
fill background directory with appropriate content.
