Ever happened to you that you downloaded and installed a rpm and then deleted the package? If your answer is yes, then there is a solution.
Come to the fairyland of rpmrebuild. Create the rpm from the installed files and give a new number if required.
sudo yum install rpmrebuild
Simplest use is to
rpmrebuild
but I personally like the one mentioned below:
rpmrebuild -R -v -P –pug-from-db

I have been looking for this for quite some time. Finally found two easy ways to do it:
:setlocal noautoindent
:setlocal nocindent
:setlocal nosmartindent
:setlocal indentexpr=
Just use the above four commands when the file is already open to stop all the indentation/smart indentation/auto indentation in vim for the current file. If you want to map it then you can use shorthand notations and map it in the .vimrc file.

delay: 2d On screen display of a command. $ date|osd_cat This is very useful if you need to show someone some text from a distance. (Like someone standing over your shoulder…)
I’d recommend aliasing it to something like:
alias osd_cat=”osd_cat -o 400 -s 8 -c blue -d 60 -f osd_cat -f -*-bitstream vera sans-*-*-*–200-*-*-*-*-*-*-*”
xosd is the utility that provides osd_cat.

Sometimes I need that for some user too. script command can be used to do this but then sometimes you cannot tell the user the session is logged or you can ask the user to run this command and it should be automatically done. And sometimes there is a need put the output in the syslog so that the root user has more control and also mail for syslog is sufficient to be analyzed rather than looking for other files. Finally I found this :
