Final Exam Topics

• Filters

• regular expressions

• Given a regular expression, understand what it will (and won't) match. (Going both ways between a regex and an English phrase)

• tr (just the simple use of tr in the 5+ pipe pipeline in the notes)
• diff
• sed

• Given a sed command, understand what the output will be.

• Awk

• Given an awk script, tell what it does.

• Shell

• Given a shell script, tell what it does.

• Perl

• Given a perl script, tell what it does.
• Know some of the main language features, especially lists, arrays, and associative arrays.
• 4 ways to initialize an associative array

• Language differences

• Know how "if-then-else if-else", for loops, etc. are constructed in each language.
• Know what $0 means in each language.
• Know what $1, $2, $3, etc. means in each language.
• I am not interested in teaching the very fine details (minutia) or rare boundary cases of syntax/semantics of a language, so focusing on that will help you at most a point or two, probably zero. I just want you to be as reasonably versed as the number of lectures and homework assignments can reasonably make a sophomore be.
