I like to code and I do it a lot. I want to build software to save the planet. Passionate polyglot programmer, generalist with specialties. Code reviewer, unit tester, driver of change. I get things done.

I make free Android apps such as Programming Quiz, websites such as bashoneliners.com, and other open source stuff. I wrote a book on Bazaar Version Control, and an article on shell tips & tricks for Linux Journal.

I blog, tweet (@janosgyerik), and post "pro tips" on CoderWall.

comment Trouble Installing APT on Centos 6 64 bit
@DavidSilvaSmith what is your real goal here? APT is a "means to an end", not really an end itself. Maybe you're asking the wrong question. If the only reason you're installing APT is to install XYZ, then maybe should be asking how to install XYZ.

Embedded board... Sounds like a restrictive environment. Can you use python, for example?

comment how to execute a python program in a shell script
@rajcoumar it's more portable this way. In some systems python might be in /usr/bin/python, in others it might be /opt/bin/python. With #!/usr/bin/env python it should work in all systems where python is correctly installed, regardless of its exact location.

comment Adding a Column of values in a tab delimited file
@Ron sed is most practical for pattern substitution and saving in-place. For your requirement of saving the file it was a relatively convenient option. If you don't need to write back to the same file you're processing, then awk is usually much easier to work with.
