Copy link

instead of line 2:

set -l du (df / | tail -n1 | sed "s/ */ /g" | cut -d' ' -f 5 | cut -d'%' -f1)

much shorter way:

set -l du (df / | grep -Eo '([0-9]{1,3})%')

2 commands in subshell instead of 5! xD
EDIT: for exact string (without "%" and without using cut) you could use

set -l du (df / | sed -En 's/.*[[:space:]]([0-9]{1,3})%.*/\1/p')
