Short Information about loaded kernel modules

Liked command 4077 so I improved it, by doing all text manipulation with sed. "Run this as root, it will be helpful to quickly get information about the loaded kernel modules." THX mohan43u Show Sample Output

Display the output of a command from the first line until the first instance of a regular expression.

Slightly simpler version of previous sed command that does the same thing. In this case, the output will stop at the command, and the entire command will be terminated as well, instead of proceeding through the whole file.

Automagically update grub.conf labels after installing a new kernel

I like to label my grub boot options with the correct kernel version/build. After building and installing a new kernel with "make install" I had to edit my grub.conf by hand. To avoid this, I've decided to write this little command line to: 1. read the version/build part of the filename to which the kernel symlinks point 2. replace the first label lines of grub.conf grub.conf label lines must be in this format: Latest [{name}-{version/build}] Old [{name}-{version/build}] only the {version/build} part is substituted. For instance: title Latest [GNU/Linux-2.6.31-gentoo-r10.201003] would turn to title Latest [GNU/Linux-2.6.32-gentoo-r7.201004]"

Alternative way to generate an XKCD #936 style 4 word password usig sed

This is what I came up to generate XKCD #936 style four-word password. Since first letter of every word is capitalized it looks a bit more readable to my eyes. Also strips single quotes. And yes - regex is a bit of a kludge, but that's the bes i could think of. Show Sample Output
