I just learned that you can use any character, not just the slash (/), for a delimitter when substituting with sed. Most unique characters should work.
This is especially useful when editing streams of file paths.
Here’s an example that modifies the path in a playlist:
cat list.m3u | sed ’s+/home/aolsen/+~/+’
The +’s worked well as a delimitter here and eliminate the need to quote the /’s
This also works in vi.

This should work on other similar systems.
su or login as root first.
# wget http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/1.5b1/linux-i686/en-US/firefox-1.5b1.tar.gz # cd /usr/lib # tar xzvf ~/firefox-1.5b1.tar.gz # mv firefox firefox-1.5b1 # which firefox /usr/bin/firefox # cd /usr/bin/ # mv firefox old.firefox # ln -s /usr/lib/firefox-1.5b1/firefox .
That should do it, and shouldn’t affect any of your launchers or file associations.
[update] It appears that you may need the compat libs for this to work. If you use a package manager, search for ‘compat’ and you should find something like compat-libstdc++ or libstdc++-compat. If you install them FF should be happy.
I found this with google earler. It’s a great document for anyone getting started with shell scripting, and I’m certain even seasoned veterans can learn a few tips.
I’m going to try to post a few howto articles for some of the simpler tasks. Many of these will be things that I use daily.
It is often necessary to read a file with bash, and act upon the entire line. There are many different ways to do this, but I’ll outline two of the simpler methods, both suitable for stacking on a single command line.
For this exercise I’ll assume the file is a list of files that we need to execute a command on.
# cat file.lst |while read line; do echo "${line}"; done /tmp/file1.txt /tmp/file with space.txt #
