I agree with Alex on the power of Perl. I like to think of the transition like this: (depending on the size of script I need) Bash - Perl - Python If the admin script is simple, I prefer to write the script in Bash. With all of the nice linux tools already written, and used daily (grep, awk, sed, cut, find), this is an easy choice. A bash script can be whipped up in a matter of minutes, and is usually just a way to batch or automate string of command lines that I could run manually. If the script need is a bit more complicated and needs a little more power, I prefer Perl. A lot of good Linux tools are written in Perl, so this would be good to know anyway. Perls terse syntax, powerful regular expressions, and CPAN are hard to beat. If the script is turning into a full fledged program, Perl can do it, but I see more and more larger projects moving to Python. Python is a bit wordy for me, and stringing several external commands is more complicated (very simple in bash an Perl), but Python does have good readability and vast libraries, and is becoming the popular choice. By the way, this transition logical also works for web development. I like PHP for easy of use and quick development time. I like Perl for sys admin stuff, but I would never use it for web development (even though PHP is descended from Perl). For large enterprise applications, Java and other tools may be more appropriate. Of course, your mileage may vary.
