Capture video of a linux desktop

Sniffing network to generate a pcap file in CLI mode on a remote host and open it via local Wireshark ( GUI ).
Then hit ^C to stop, get the file by scp, and you can now use wireshark like this : $ wireshark /tmp/sniff.pcap If you have tshark on remote host, you could use that : $ wireshark -k -i

Coping files, excluding certain files
Preserve file structure when coping and exclude some file o dir patterns

Download all manuals RedHat 7 (CentOS/Fedora) with one command in Linux

Check a server is up. If it isn't mail me.
For some reason the 2&>1 does not work for me, but the shorter stdout/stderr redirection >& works perfectly (Ubuntu 10.04).

Stamp a text line on top of the pdf pages.
To quickly add some remark, comment, stamp text, ... on top of (each of) the pages of the input pdf file.

Finds executable and existing directories in your path that can be useful if migrating a profile script to another system. This is faster and smaller than any other method due to using only bash builtin commands.

Sort movies by length, longest first
handles file names with spaces and colons, fixes sort (numeric!), uses mplayer, same output format as other alternatives

shows history of logins on the server
perfect on a crashed system where you can't use commands like last. for investigation purposes wtmp file can be copied over to a different server and read with utmpdump

Get all mac address
I prefer the ip command to ifconfig as ifconfig is supposedly going to be deprecated. Certain IP address aliases can only be seen with the ip command (such as the ones applied by RHCS).
