Squeeze Repeated Spaces

Text Processing · easy · solved in-browser (no VM needed) · 3 tiered hints

Write /home/player/squeeze.sh: a bash script that reads /opt/data/messy.txt and collapses every run of repeated space characters into a single space, printing the result to stdout. Use tr with the -s (squeeze) option on the space character. (Authored config, graded structurally — the engine isn't run here.)
