The HELL that find is!

Short tutorial on Linux find command.

• To remove all files named 'a.out' or '*.o' that have not been accessed for a week:
• find / \( -name a.out -o -name '*.o' \) -atime +7 -exec rm {} \;
• The rm command is executed once for each file.
• find / \( -name a.out -o -name '*.o' \) -atime +7 -exec rm {} +
• To find all files below the directory 'documents' that contain the regular expression 'string':
• find documents -type f -exec grep string {} +
• To find all files in the directory 'home', not descending into its subdirectories:
• find home ! -name home -prune
• To check whether the file 'diary' has been updated within the last two days; the name of the file is printed if true, and is not printed otherwise:
• find diary -prune -mtime -2

HP-UX Tips

HP-UX adminsitrative tips, solution to frequently occuring problems.

Firefox 1.0+ Tab Switching

If you miss switching tabs with CTRL+1, CTRL+2 ... CTRL+N key combinations from Firefox Keyconfig extension. It lets you modify some (not all) default key bindings. It is also possible to create new keybindings. You can create new keybindings from the Keyconfig dialog (Tools->Keyconfig). Then enter the following code in the code box. After that press CTRL+1 in the key capture textbox.

/* CODE */
gBrowser.mTabContainer.selectedIndex=0;

This will let you switch to Tab 1 by pressing CTRL+1. For Tab 2 do the same with selectedIndex value set to 1 and so on.
