I\'m trying to write a bash script that increments the version number which is given in

{major}.{minor}.{revision}

For example.

Answer 1

Pure Bash using an array:

version='1.2.33'
a=( ${version//./ } )                   # replace points, split into array
((a[2]++))                              # increment revision (or other part)
version="${a[0]}.${a[1]}.${a[2]}"       # compose new version
