Folks,

    can someone tell me which package provides the substr command line
routine?

TIA,

Jim

You can look for yourself by following the "setup.exe Package Listing"
link from http://cygwin.com/ .

In this case, you probably want sed, gawk, or Perl, there is no UNIX
command 'substr'.

from the commandline you can use 'expr substr <string> <begin> <length>'

it's crude and OT but I just happened to need it today so I remembered this.

Dear Elegant,

Please be specific about what program implements the "expr substr" command. 
The phrase "the command line" is not singly defined on any Unix (or 
Unix-like) system extant today.

In this case, it's TCSH, which is not the default Cygwin shell (BASH is).

'usr/bin/expr.exe' is provided by sh-utils ( 
http://cygwin.com/cgi-bin2/package-cat.cgi?file=sh-utils/sh-utils-2.0-2&grep=expr 
)

I'm not exactly sure if it is a builtin of tcsh/bash/ksh/ash, but I do 
know it should be available outside a shell on a system that uses SUSv2 
( http://www.opengroup.org/onlinepubs/007908799/xcu/expr.html ) as a 
guideline(which Cygwin as a distribution tries to do AFAIK).

When I wrote my earlier post I didn't have a web connection but I did 
double check on a HP-UX ksh terminal that it should work as I thought it 
would. It even works using from a cmd.exe shell from W2K.

Re: substr

Gilgamesh,

Two mistakes on my part:

1) Your name--I'm sorry about that

2) Assuming that "expr" is a shell built-in. It's not.
