Check These Out
Trace python statement execution and syscalls invoked during that simultaneously
If you wish to launch the kde4 screen saver without the password prompt to exit, use this command:
$ qdbus org.freedesktop.ScreenSaver /ScreenSaver org.freedesktop.ScreenSaver.SetActive True
Also can be done with:
$ /usr/lib/kde4/libexec/kscreenlocker --forcelock
Usefule to check whether SELinux is in force or disabled.
Though you need to be superuser while execute this command.
Today I needed to choose an icon for an app. My simpler way: put all of /usr/share/icons in myicons folder and brows'em with nautilus. Then rm -r 'ed the entire dir.
The biggest advantage over atoponce's nifty original is not killing the scrollback. Written assuming bash, but shouldn't be terribly difficult to port to other shells. S should be multiple spaces, but I can't get commandlinefu to save/show them properly, any help?
I'll let Slayer handle that. Raining Blood for your pleasure.
I was surprised to find that with RedHat bash, I could not find any comment lines (begining with #) in my bash shell history. Surprised because in Mageia Linux this works. It turns out that RedHat's bash will keep comment lines if in my .bashrc, I define:
export HISTIGNORE=' cd "`*: PROMPT_COMMAND=?*?'
Why have comment lines in shell history? It's a handy and convenient way to make proto-commands (to be completed later) and for storing brief text data that is searchable in shell history.
This does the following:
1 - Search recursively for files whose names match REGEX_A
2 - From this list exclude files whose names match REGEX_B
3 - Open this as a group in textmate (in the sidebar)
And now you can use Command+Shift+F to use textmate own find and replace on this particular group of files.
For advanced regex in the first expression you can use -regextype posix-egrep like this:
mate - `find * -type f -regextype posix-egrep -regex 'REGEX_A' | grep -v -E 'REGEX_B'`
Warning: this is not ment to open files or folders with space os special characters in the filename. If anyone knows a solution to that, tell me so I can fix the line.
