Top Forums Shell Programming and Scripting BASH regex (convert from working perl version) Post 302361401 by radoulov on Tuesday 13th of October 2009 06:14:38 AM

Which bash version? If I recall correctly 3 and above offers support for regular expressions:

Code:
for v in 'ko=a|b' 'ok=0_/'; do
  [[ $v =~ ^[[:alpha:]]+=[./[[:alnum:]_-]+$ ]] &&
    printf '$v is ok: %s\n' "$v" ||
          printf '$v is not ok: %s\n' "$v"
done

The above outputs:

Code:
$v is not ok: ko=a|b
$v is ok: ok=0_/

NAME
XS::APItest - Test the perl C API SYNOPSIS
use XS::APItest; print_double(4); ABSTRACT
This module tests the perl C API. Currently tests that "printf" works correctly. DESCRIPTION
This module can be used to check that the perl C API is behaving correctly. This module provides test functions and an associated test script that verifies the output. This module is not meant to be installed. EXPORT Exports all the test functions: print_double Test that a double-precision floating point number is formatted correctly by "printf". print_double( $val ); Output is sent to STDOUT. print_long_double Test that a "long double" is formatted correctly by "printf". Takes no arguments - the test value is hard-wired into the function (as "7"). print_long_double(); Output is sent to STDOUT. have_long_double Determine whether a "long double" is supported by Perl. This should be used to determine whether to test "print_long_double". print_long_double() if have_long_double; print_nv Test that an "NV" is formatted correctly by "printf". print_nv( $val ); Output is sent to STDOUT. print_iv Test that an "IV" is formatted correctly by "printf". print_iv( $val ); Output is sent to STDOUT. print_uv Test that an "UV" is formatted correctly by "printf". print_uv( $val ); Output is sent to STDOUT. print_int Test that an "int" is formatted correctly by "printf". print_int( $val ); Output is sent to STDOUT. print_long Test that an "long" is formatted correctly by "printf". print_long( $val ); Output is sent to STDOUT. print_float Test that a single-precision floating point number is formatted correctly by "printf". print_float( $val ); Output is sent to STDOUT. call_sv, call_pv, call_method These exercise the C calls of the same names. Everything after the flags arg is passed as the the args to the called function. They return whatever the C function itself pushed onto the stack, plus the return value from the function; for example call_sv( sub { @_, 'c' }, G_ARRAY, 'a', 'b'); # returns 'a', 'b', 'c', 3 call_sv( sub { @_ }, G_SCALAR, 'a', 'b'); # returns 'b', 1 eval_sv Evaluates the passed SV. Result handling is done the same as for "call_sv()" etc. eval_pv Exercises the C function of the same name in scalar context. Returns the same SV that the C function returns. require_pv Exercises the C function of the same name. Returns nothing. SEE ALSO
