Increment version text stored in a bash script file
Solution 1:
awk -F'[ .]' '/^echo version/ {print $1,$2,$3"."$4"."$5+1}' ~/.bashrc
Output:
echo version 1.0.2
-F'[ .]': field separator(s) blank and dot
/^echo version/: search for line starting (^) with echo version
print $1,$2: print strings separated by a blank
$5+1: increment string/value by 1
Solution 2:
perl to the rescue
$ cat file
echo version 1.0.1
$ perl -i -pe 's/echo version \d+\.\d+\.\K(\d+)/ $1+1 /e' file
$ cat file
echo version 1.0.2
