Shell script One-Liners

May, 2019

Handy shell scripts - you do have a command line don't you?

# remove space from file names in current directory
for f in *\ *; do mv "$f" "${f// /_}"; done

# prepend string "Series_" to file names: 
for f in *.txt; do mv "$f" "Series_$f"; done

# built-in calculator   - on zsh at least
print $(( 2 * 7));  print $(( 2 ** 8));
