Can anyone explain what is :~1% in the below statement in a batch file? I assigned the value of %variable to servername and tried echo %variable. I get the same server name as output. Can anyone explain how the statement below works?
set variable=%variable:~1% this is notation for subs string expansion , look at this out put form command line you will understand.
C:\>set temp=stackoverflow.com C:\>echo %temp% stackoverflow.com C:\>echo %temp:~5% overflow.com C:\>echo %temp:~5,8% overflow C:\> if you have not understood , here is syntax (in my words)
set variable=%variable:~startingCharector [,OptionalLenghtOfCharctors]% where
OptionalLenghtOfCharctors by default it takes remaining characters of string.
It's a syntax for substrings from the variable contents, in this case it removes the first character.
See set /? for help
