Temporarily Clearing Environment Variables

After a long break I have some more ideas…. Will be posting them soon. For now, I leave you with a command to clear your current environment:

root@67 [~]# printenv | wc -l
26
root@67 [~]# env -i printenv | wc -l
0

This is very useful when you want to run a command ignoring any environment variables you have set. I use this command with curl nearly everyday to ignore the http_proxy environment variable I have set. Another, longer, option is:

root@67 [~]# http_proxy="" curl ....

I prefer env -i as its simpler.

Splitting Strings Natively with the Shell: Why 2 years 14 weeks ago

Today I want to discuss splitting strings into tokens or “words”. I previously discussed how to do this with the IFS variable and promised a more in depth discussion. Today, I will make the case on WHY to use IFS to split strings as opposed to using a subshell combined with awk or cut.

Reduce Pdf size through Command Line 2 years 13 weeks ago

If you want to reduce PDF file size using command line you can use ghostscript. Ghostscript is used for PostScript/PDF preview and printing.
