Top Forums Shell Programming and Scripting Replace all string matches in file with unique random number Post 303024272 by apmcd47 on Friday 5th of October 2018 04:23:00 AM

Untested.
Code:
#!/bin/bash
rndm=($(shuf -e {00..99}))
while read line
do
   if [[ "$line" =~ ^Test ]]
   then
      printf "%s%s\n" Test ${rndm[10#${line#Test}]}
   else
      printf "%s\n" "$line"
   fi
done < infile > outfile

Creates a pseudo-random list of numbers 00-99 and uses the value of the current number in the test line to index the new number.

The 10# is required to stop bash from evaluating 08 and 09 as invalid octal numbers and instead evaluate them as valid decimals.

XS::APItest(3pm)					 Perl Programmers Reference Guide					  XS::APItest(3pm)

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.
