There is a package called psmisc that provides a useful application fuser. The package provides the below (on fedora):
/sbin/fuser
/usr/bin/killall
/usr/bin/peekfd
/usr/bin/pstree
/usr/bin/pstree.x11
There are couple of options you can provide on the terminal to fuser. The main purpose of the binary is to check the process id of the process using the file. This can be useful if some file operation on a file is blocking something for you 🙂
Continue readingI was trying to get templates to work on evolution and found that although templates are there in evolution mail client, its not that efficient to use. What I thus wanted was to have something that could allow me to send mails to (and cc and bcc) to specified people with predefined template, only some values changed, like changelog and so on.

Running this monotonously every day is quite boring, so comes to rescue is logwatch. I have <a class="zem_slink freebase/en/fedora" title="Fedora" rel="homepage" href="http://fedoraproject.org/">Fedora <a class="zem_slink freebase/en/installation" title="Installation (computer programs)" rel="wikipedia" href="http://en.wikipedia.org/wiki/Installation_%28computer_programs%29">installation so I will talk about the location with respect to that so for your distribution it might be a little different.

Been pretty busy for last couple of days. Will be busy for another few days, but here’s something to munch in the meantime (Script may need changes depending on the type of file you want to download or the site you are browsing, but the chnages should be minimal):
file=”/tmp/temp.dir”

wget ”$url” -O $file -o /dev/null
I generally use vi/vim for all my practical purposes of working with text files. And I have all the vi/vim plugins required to work with the files. This causes the following to be in the skeleton for all the bash scripts that I create:
set -o nounset                             # Treat unset variables as an error
With this all the unbound variables as errors and was problem with all the shell scripts that was being sourced in the startup of bash. So all I had to do was remove this from all the startup scripts and then from the skeleton of the bash script in vim :).
