This is purely longhand to show a way of building up each line ready for use.
There are no loops nor the usage of the mv command.
It uses __builtins__ only and is step by step in the code shown/
It is a little tongue-in-cheek but shows the power of the shell.
OSX 10.7.5, default bash terminal.
Code:
#/bin/bash
echo "1977SSD_rsdIUIUYIU2345tst.pdf
1976SDP_rstdtYsr.pdf
1943FDT_rstt.pdf
1996DFF_stdstrd.pdf" > /tmp/text
# Save IFS for later.
ifs_str="$IFS"
IFS="

read -d '' -r text < /tmp/text
echo "$text"
# This is purely longhand using builtins; set up an array using newlines only as a separater...
arr=($text)
# First array.
length="${#arr[0]}"
echo "$length"
txt="_${arr[0]:4:3}"
echo "$txt"
rename="${arr[0]:0:4}${arr[0]:7:$[ ( $length - 11 ) ]}$txt${arr[0]:$[ ( $length - 4 ) ]:4}"

LEARN ABOUT PHP
parse_str
PARSE_STR(3) 1 PARSE_STR(3)parse_str - Parses the string into variablesSYNOPSIS
void parse_str (string $str, [array &$arr])
DESCRIPTION
Parses $str as if it were the query string passed via a URL and sets variables in the current scope.
Note
To get the current QUERY_STRING, you may use the variable $_SERVER['QUERY_STRING']. Also, you may want to read the section on vari-
ables from external sources.
Note
The magic_quotes_gpc setting affects the output of this function, as parse_str(3) uses the same mechanism that PHP uses to populate
the $_GET, $_POST, etc. variables.
PARAMETERS
o $str
- The input string.
o $arr
- If the second parameter $arr is present, variables are stored in this variable as array elements instead.
RETURN VALUES
No value is returned.
EXAMPLES
Example #1
Using parse_str(3)
<?php
$str = "first=value&arr[]=foo+bar&arr[]=baz";
parse_str($str);
echo $first; // value
echo $arr[0]; // foo bar
echo $arr[1]; // baz
parse_str($str, $output);
echo $output['first']; // value
echo $output['arr'][0]; // foo bar
echo $output['arr'][1]; // baz
?>
