    bash scripting?

    I am writing a bash script to do some basic database operations. I am not familiar with all of bash scripting's abilities yet. Can I edit specific lines and portions of lines in a file with bash scripting or do I need to use something else? I would do the whole thing in C but I want to use cron to autoupdate the database

    cron is not limited to only running bash scripts you know...

    It's pretty much the same problem as in C. If you want to change a text file, you read it in, make some changes, and write it out.

    Simple edits can usually be achieved with 'sed'.
    For more complicated text manipulations, I usually use Perl.

    Like I said, it doesn't "need" to be something else just to make it runnable from cron.

    As with many tools, there is considerable overlap in the capabilities, so I guess you should start with the ones you feel comfortable using.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.
