Ahh. That's what I get for not reading the original post carefully.

This is a sample of what I really have on the file there are more spaces than the ones that you can check here.
Code:
#  ISSUER CODE: QPPS                              
#  FROM DATE: 20090224                         
#  TO DATE: 00000000                                
#  SEQUENCE NUMBER: 01

cfajohnson posted this script that works fine with only one problem.
Code:
{
 IFS=:
 read q a
 read q b
 read q c
 read q d
} <  RSA_RECORDS.txt

filename=${a# }_${b# }_${c# }_${d# }.txt

cp RSA_RECORDS.txt "$filename"

I doesn't trim the right side spaces.


Does anyone have another idea of a Bash Script that can work with this. I also have AWK and SED on the server nothing else.


Thanks in advance, I really need a solution ASAP, I had tried many hours trying to trim that space without any luck.

Code:
read q a; set -- $a; a=$1
read q b; set -- $b; b=$1

Or:

Code:
_trim () 
{ 
    _TRIM=$1;
    trim_string=${_TRIM%%[!${2:- }]*};
    _TRIM=${_TRIM#"$trim_string"};
    trim_string=${_TRIM##*[!${2:- }]};
    _TRIM=${_TRIM%"$trim_string"}
}

read q a; _trim "$a"; a=$_TRIM
read q b; _trim "$b"; b=$_TRIM

Etc., etc, ...

This is the full code of the working script if anyone else is looking for something similar.

Code:
#/bin/sh

_trim () 
{ 
    _TRIM=$1;
    trim_string=${_TRIM%%[!${2:- }]*};
    _TRIM=${_TRIM#"$trim_string"};
    trim_string=${_TRIM##*[!${2:- }]};
    _TRIM=${_TRIM%"$trim_string"}
}


{
 IFS=:
 read q a; _trim "$a"; a=$_TRIM
 read q b; _trim "$b"; b=$_TRIM
 read q c; _trim "$c"; c=$_TRIM
 read q d; _trim "$d"; d=$_TRIM
} < HASH.out 



filename=${a}_${b}_${c}_${d}.txt



cp HASH.out "$filename"


Thanks Johnson
