Open all files which have some string go directly to the first line where that string is and run command on it.
Other examples:
Run vim only once with multiple files (and just go to string in the first one):
grep -rl string_to_find public_html/css/ | xargs vim +/string_to_find
Run vim for each file, go to string in every one and run command (to delete line):
grep -rl string_to_find public_html/css/ | xargs -I '{}' vim +/string_to_find {} -c ":delete"
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]"
