rename files Ax based on strings found in files Bx

Hi,

I'm not very experienced in shell scripting and that's probably why I came across the following problem:

I do have several hundred pairs of text files (PF00x.spl and PF00x.shd) where the first file (PF00x.spl) needs to be renamed according a string that is included in the second file (PF00x.shd).

Example:

PF00x.shd contains a string (length varies from file to file; example would be: AB09098765 7 6 5) within the follwing keywords "bviwacsbviwacs" and "Adb"

The goal is to rename PF00x.spl to AB09098765 7 6 5.spl and so on for the remaining files.

I hope my description makes sense... any suggestions how I could solve that problem?

Thanks a lot!

give some example lines from the second file rather than describing them

Here you go (extract from PF001.shd):

2H&   2H& b v i w a c s b v i w a c s s m u A B 4 6 2 6 6 7 _ 2 0 0 9 0 8 1 4 7 3 9 4 3 7 1 0 - B e r i c h t A d b P L F A d b \ \ P C 2 6 7 I W A C S

And I'm looking for the string marked bold.

Thanks,

This works in ksh when run in the same directory as the target files: -

Code:
ls *.shd | while read FILE_NAME
do
        if [[ -w ${FILE_NAME%.*}.spl ]] ## Ignore any file with no .spl file
        then
                NEW_FILE_NAME=$( nawk ' BEGIN {
                        ## Spaces in target strings ????
                        first = "b v i w a c s b v i w a c s"   
                        last = "A d b"
                }
                ( $0 ~ first ) && ( $0 ~ last ) {
                        startm = index( $0, first ) + length( first )
                        endm = index( $0, last ) - 1
                        file_name = substr( $0, startm, endm - startm )
                } END {
                        ## Remove spaces from new file name
                        gsub( / /, "", file_name )              
                        print file_name
                } ' $FILE_NAME).spl

                ## Copy. change cp to mv if required
                cp ${FILE_NAME%.*}.spl $NEW_FILE_NAME           
        else
                echo "File ${FILE_NAME} has no matching .spl file"
        fi
done

Your first post had no spaces in the enclosing strings but your second did as well as having unprintable characters so I created a test file with spaces in as a worst case. Running the code as a script called "inch" with these files: -

Code:
TX5XN:/home/brad/forum/inch>ls -l
total 8
-rwxrwxrwx 1 brad root 682 2009-10-07 20:07 inch
-rw-r--r-- 1 brad root 143 2009-10-07 18:50 PF00x.shd
-rw-r--r-- 1 brad root   0 2009-10-07 19:37 PF00x.spl
-rw-r--r-- 1 brad root   0 2009-10-07 19:59 PF01x.shd

Gave this output: -

Code:
TX5XN:/home/brad/forum/inch>inch
File PF01x.shd has no matching .spl file

TX5XN:/home/brad/forum/inch>ls -l
total 8
-rwxrwxrwx 1 brad root 682 2009-10-07 20:07 inch
-rw-r--r-- 1 brad root 143 2009-10-07 18:50 PF00x.shd
-rw-r--r-- 1 brad root   0 2009-10-07 19:37 PF00x.spl
-rw-r--r-- 1 brad root   0 2009-10-07 19:59 PF01x.shd
-rw-r--r-- 1 brad root   0 2009-10-07 20:11 smuAB462667_2009081473943710-Bericht.spl
