Sorting strings with numbers in Bash [duplicate]
Solution 1:
Execute this
sort -t _ -k 2 -g data.file
- -t separator
- -k key/column
- -g general numeric sort
Solution 2:
I think this is a GNU extension to sort, but you're looking for the --version-sort (or -V) option:
$ printf "prefix%d\n" $(seq 10 -3 1)
prefix10
prefix7
prefix4
prefix1
$ printf "prefix%d\n" $(seq 10 -3 1) | sort
prefix1
prefix10
prefix4
prefix7
$ printf "prefix%d\n" $(seq 10 -3 1) | sort --version-sort
prefix1
prefix4
prefix7
prefix10
