UNIX for Beginners Questions & Answers

Hi Guys,
am trying to write logic to do incremental value using linux
Example:

Code:

a=00.00.00.01

My b should be like this

Code:

b=00.00.00.02

and when it reaches 99 my b should look like this

Code:

b=00.00.01.99

Appreciate your help guys

Hi , Am trying bump the SNAPSHOT version in pom.xml , My company is APERVI
This is what i tried

Code:

 a=00.00.00.01
 b=`echo $a | cut -d"." -f1,2,3`"."`expr \`echo $a | cut -d"." -f4\` + 1`
echo $b
00.00.00.2

Here is a tutorial showing how to use CODE and ICODE tags:

What operating system and shell are you using?

Have you considered using awk?

Do you really want to go from 00.00.00.99 to 00.00.01.99 or do you really want to go to 00.00.01.00? That is, is the intent to always have each element of the version number be a two-digit number where low order elements count from 00 through 99 and then resets to 00 when incrementing the next higher element? Or, does an element of the version number lock at 99 when the next higher order element increments from 00 through 99 as shown in post #1?

No I haven't tried awk , I think I would like to go 00.00.01.00 once it reached 00.00.00.99

I repeat: "What operating system and shell are you using?"

And, where is this version number stored? Are you reading it from a file, or is it stored in a variable in your shell script?
