Hello,

Could you please try the following code. Let's say change_number is the file which have input data.

awk -vs1="VERSIONNUMBER ="1"" '/VERSIONNUMBER =/ gsub(/VERSIONNUMBER ="2"/,s1)' change_number

Output will be as follows.

<SHORTCUT  OBJECTSUBTYPE ="" OBJECTTYPE  VERSIONNUMBER =1/>
< OBJECTTYPE REPOSITORYNAME ="" VERSIONNUMBER ="4"/>
REFERENCETYPE ="LOCAL"  VERSIONNUMBER ="1"/>
REFERENCETYPE ="LOCAL"  VERSIONNUMBER =1/>
<CONFIG DESCRIPTION ="Default VERSIONNUMBER ="1">

Thanks,
