Increase number delimited with dots from params file

Question

I have few params in my params.txt

config_version = "1.2.3" 

test_version = "1.2.3" 

version_count = "1.2.3" 

service_name = "test"

already have answer from this forum how to get this number as output:

awk 'BEGIN{FS="[ \"]+"}/config_version =/{print $3}' /dir/params.txt

I need to increase number of config_version value +1 for each awk one liner run. Examples:

first value is 1.2.3, after awk command run --> 1.2.4 and save back to file

first value is 1.200.1, after awk command run --> 1.200.2 and save back to file

first values is 8.999.99, after awk command run --> 9.000.0 and save back to file

after each run of awk command the params.txt config_version will be updated to increased value

params.txt after 5 awk script execution:

config_version = "1.2.8" 

test_version = "1.2.3" 

version_count = "1.2.3" 

service_name = "test"

It all runs on Gitlab CI and only one-liner will be the option I can use.

"Gitlab job run (1) -> take 1.200.0 -> change to 1.200.1"

"Gitlab job run (2) -> take 1.200.1 -> change to 1.200.2"

"Gitlab job run (10) -> take 1.200.9 -> change to 1.201.0"

"Gitlab job run (xx) -> take 1.999.9 -> change to 2.000.0"

Command will run as a one liner in gitlab ci

Answer 1

$ cat version.txt
1.2.3
$ awk -F. 'BEGIN{ OFS="." }{ $3++; if ($3>9){ $2++; $3=0 }; print $1,$2,$3 }' version.txt
1.2.4

Now I should explain this code, but it's to simple to explain. 😕😉

EDIT:

• this looks for "config_version"
• this uses gawk
• this is a one-liner

awk 'BEGIN{ OFS="." }/config_version/{match($0,/([0-9]+)+.([0-9]+)+.([0-9])+/,a); a[3]++; if(a[3]>9) { a[3]=0; a[2]++ }; if(a[2]>999){ a[2]=0; a[1]++ }; print "config_version = \"" a[1],a[2],a[3]"\""}!/config_version/'  version.txt > version.tmp; cp version.tmp version.txt

or (just for better readability)

awk 'BEGIN{ OFS="." }
     /config_version/{match($0,/([0-9]+)+.([0-9]+)+.([0-9])+/,a);
       a[3]++; 
       if(a[3]>9) { a[3]=0; a[2]++ }; 
       if(a[2]>999){ a[2]=0; a[1]++ }; 
       print "config_version = \"" a[1],a[2],a[3]"\""}
     !/config_version/'  version.txt > version.tmp; cp version.tmp version.txt

• lines match config_version will be matched, and incremented
• lines match config_version will be copied without change
• output is send to version.tmp. If you use version.txt as output you will be left with a zero byte length file..
