With this you can unlock your KDE4 session via SSH, via mobile phone SSH or e. g. scheduled task in crontab (without asking password). Useful when you need to grant somebody access to your locked profile remotely.

Create an alias (e. g. as "unlock") and use with remote KDE4 lock.

This works only on KDE4 boxes because KDE 3 is using utility with another name.

Tested on Kubuntu 8.10.

Forgot to lock your computer? Want to lock it via SSH or mobile phone or use it for scheduled lock?

TIP: Make a alias for this (e. g. as "lock").

I found some howtos for ugly X11 lock, but this will use regular KDE locking utility.

Note that KDE 3 is using utility with another name (I guess with the same argument --forcelock)

Tested on Kubuntu 8.10.

Stay tuned for remote unlock.

Tuned for short command line - you can set the path to sessionstore.js more reliable instead of use asterixes etc.

Usable when you are not at home and really need to get your actual opened tabs on your home computer (via SSH). I am using it from my work if I forgot to bookmark some new interesting webpage, which I have visited at home. Also other way to list tabs when your firefox has crashed (restoring of tabs doesn't work always).

This script includes also tabs which has been closed short time before.

You need python-scapy package

Run GUI apps on another machine remotely through SSH.

-C is for data compression and -X enables X11 forwarding.

The curl command retrieve the HTML text containing the IP address. The grep command picks out the IP address from that HTML text.

This is one way to find out.

This is a simple command for jumping to the matching brace, square bracket, or parentheses. For example, it can take you from the beginning of a function to the end with one key stroke. To delete everything between the pairs of {}, [], or (), issue the command:

To replace text between pairs of braces, brackets, or parentheses, issue the command:

You can also use this command to find out if an opening brace has been properly closed.

Get max number of arguments that can be accepted by the exec() system call.

Scan for viruses, recursively and print only infected files, with bell sound. Clamscan is part of clamav package. Tested on Debian.

The "pstree" command uses special line-drawing characters. However, when piped into the "less" pager, these are normally disabled.

This uses Bash's "process substitution" feature to compare (using diff) the output of two different process pipelines.

Get your colorized grep output in less(1). This involves two things: forcing grep to output colors even though it's not going to a terminal and telling less to handle those properly.

The "find" command can be annoying when used inside of a Subversion (or CVS) working directory. Obviously, you can combine this with other predicates and commands to create a more elaborate pipeline:

Note: You can use my "dont-go-there.sh" script to wrap the "find" command and do this automatically at http://forwardlateral.com/blog/2006/02/27/dont-go-there/

-l outputs only the file names

-i ignores the case

-r descends into subdirectories

Displays SuSE release information

I find that I create a directory and then cd into that directory quite often. I found this little function on the internets somewhere and thought I'd share it. Just copy-paste it into you ~/.bash_profile and then `source ~/.bash_profile`.

get a list of temps of your hard-drives.

Unset TMOUT or set it to 0 in order to prevent shell autologout. TMOUT is the number of seconds after which the present shell will be killed if it has been idle for that long.

this will cause any commands that you have executed in the current shell session to not be written in your bash_history file upon logout
