This adds all new files to SVN recursively. It doesn't work for files that have spaces in their name, but why would you create a file with a space in its name in the first place?

Change the number to change the number of spaces. Leaving it out defaults to 8. Leaving out the filename defaults to stdin.

And to do it in reverse, you can use the unexpand command.

Functions: echo return which

This function is used to set environmental variables from a list of alternatives depending on what's installed on the system. It returns the first program found in the list.

Example usage:

export BROWSER=$(find_alternatives chromium-browser google-chrome opera firefox firefox-bin iceweasel konqueror w3m lynx)

Use it with cat and '|' for know what is used in a conf file.

For example cat /etc/squid/squid.conf | sed -re '/^#/d ; s/#.*$// ; /^\s$/d' :

Show you what you use in your file conf.

It removes all comments and empty lines.

Empty lines are lines with nothing, a tab, or a space.

It will produce passwords with length of 20 printable characters within a reasonable time.

For shorter or longer passwords just change the 20 in bs=20 to something more convenient.

To create only alpha numeric passwords change [:print:] to [:alnum:]
