Hi,

I want to truncate a string variable, returned in the script. In perl I used the below and it worked.

BRNo=BR12345
$BR = substr($BRNo, 2, 7)

How can I do it in sh.

Thanks !

Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSuUser(Contributed Perl DocumPerl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr(3)

NAME
Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr - Use 4-argument "substr" instead of writing "substr($foo, 2, 6) = $bar". AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
Conway discourages the use of "substr()" as an lvalue, instead recommending that the 4-argument version of "substr()" be used instead. substr($something, 1, 2) = $newvalue; # not ok substr($something, 1, 2, $newvalue); # ok The four-argument form of "substr()" was introduced in Perl 5.005. This policy does not report violations on code which explicitly specifies an earlier version of Perl (e.g. "use 5.004;"). CONFIGURATION
This Policy is not configurable except for the standard options. SEE ALSO
"substr" in perlfunc (or "perldoc -f substr"). "4th argument to substr" in perl5005delta AUTHOR
