Hands-On Labs

Lab 1: Review basic UNIX commands.

Lab 2: Query, create, and control foreground, background, and suspended
processes.

Lab 3: Use Regular Expressions to find and replace matching text strings in
files and I/O streams.

Lab 4: Use the power tools: grep, sed, and awk.

Lab 5: Create user interactive shell programs.

Lab 6: Redirect/pipe stdout and stderr of commands.

Lab 7: Create conditional branching shell programs.

Lab 8: Use shell structures if, while, for, and case to create scripts.

Lab 9: Search file subtree, sort with multiple keys, and translate text.

Lab 10: Use utilities wc, diff, cmp, split, od, strings, fmt, seq, printf, and
paste.

Lab 11: Schedule a script written to check disk capacity.

Lab 12: Find and run X applications.
