About
A small filter. It keeps only the fields, bytes or characters you name and drops the rest. It works on a fixed delimiter or on character positions, which suits simple, regular data.

Included with Termux

cut -d: -f1 users.txt Split each line on a colon and keep only the first field. cut -d, -f2,4 data.csv Keep the second and fourth comma-separated columns. The rest are dropped. cut -c1-10 notes.txt Keep only the first ten characters of every line. cut -f3 --complement report.txt Print everything except the third field. cut -s -d: -f1 users.txt Skip lines with no delimiter at all. That avoids stray output. cut --output-delimiter=" " -d: -f1,7 users.txt Rejoin the kept fields with a different separator. Worked example
Run cut -d, -f2,4 data.csv and this is what you should see.
$ cut -d, -f2,4 data.csv
