In case you forgot to read the forum rules, here is quick copy.
Quote:
RULES OF THE UNIX AND LINUX FORUMS
(1) No flames, shouting (all caps), sarcasm, bullying, profanity or arrogant posts.
(2) No negative comments about others or impolite remarks. Be patient.
(3) Refrain from idle chatter that does not contribute to the knowledge base. This does not apply to the forums in The Unix Lounge which are for off-topic discussions.
(4) Do not 'bump up' questions if they are not answered promptly. No duplicate or cross-posting and do not report a post or send a private message where your goal is to get an answer more quickly.
(5) Search the forums database with your keywords before asking.
(6) Do not post classroom or homework problems.
(7) No job postings from headhunters or recruiters except in The Unix Forums Job Board. See How to Post to The UNIX Forums Job Board for information on using the Job Board.
(8) No BSD vs. Linux vs. Windows or similar threads.
(9) Edit your posts if you see spelling or grammar errors (don't write in cyberchat or cyberpunk style). English only.
(10) Don't post your email address and ask for an email reply. Don't send a private message with a technical question. The forums are for the benefit of all, so all Q&A should take place in the forums.
(11) Post questions with descriptive subjects. For example, do not post questions with subjects like "Help Me!", "Urgent!!" or "Doubt". Post subjects like "Execution Problems with Cron" or "Help with Backup Shell Script".
(12) These are not hacker boards so hacker related posts will be promptly deleted or moderated.
(13) The forum administrators reserve the right to prune, move or edit posts that do not adhere to the rules or are technically inaccurate.
(14) The forum administrators reserve the right to remove users or change their posting status to read only without notice if any rules are not followed.
I tried to adapt your code but I always get only one file named ".SPL" even when I change the keywords to a single letter for testing purposes...
Seems like I'm doing something the wrong way.
Additional background information: I currently have to use cygwin with bash on WinXP...
Therefore I amended the code as listed at the end of this post.
The keywords are b v i w a c s b v i w a c s (at least when I'm looking at them in bash) and A d o b e
the result I'm looking for would be smuAB462691_200908148 19 27 296 - Bericht.SPL
I've attached two files (one spl and one original shd) for illustration. It would be great if you could take a short look at them.
Well this turned out to be more interesting than I originally thought it would be: -
When I got your file I found it would not behave with awk or sed or any of the usual utilities so I took a look at its internal structure by doing an octal dump of the contents.
Here is the part containing your start string with the individual letters highlighted in bold: -
Code:
TX5XN:/home/brad/forum/inch>od -c FP00000.SHD | pg
0003440 H & 375 032 001 002 \0 \0 b \0 v \0 i \0 w \0
0003460 a \0 c \0 s \0 \0 \0 b \0 v \0 i \0 w \0
0003500 a \0 c \0 s \0 \0 \0 s \0 m \0 u \0 A \0
As you can see each letter is delimited by a number 0 or null, so anything like awk or sed will fail as they look for string based files, not null delimited chars.
This is why your original paste of the file contained so many unprintable characters and spaces between each letter of your target string.
Having established the problem it is now a simple fix, just remove the nulls prior to manipulating the strings: -
Code:
TX5XN:/home/brad/forum/inch>tr -d "\000" < FP00000.SHD | strings
Adobe PDF
PRIV
EBDA
Standard
bviwacsbviwacssmuAB462691_200908148 19 27 296 - BerichtAdobe PDFAdobe PDF ConverterWinPrintNT EMF 1.008\\PC267IWACS
So adding the stripping of the nulls to the tool gives us the ability to correctly process the string we want to turn into a file name: -
ls *.SHD | while read FILE_NAME
do
if [[ -w ${FILE_NAME%.*}.SPL ]] ## Ignore any file with no .SPL file
then
NEW_FILE_NAME=$( tr -d "\000" < $FILE_NAME | strings | nawk ' BEGIN {
## Spaces in target strings ????
first = "viwacsbviwacs"
last = "Adobe"
}
( $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
} ' ).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
Note there is no real error checking for existing files etc, I will leave you to add that yourself.
You should also note it needs to be run in the target directory so you will need to modify it if you want to handle multiple directories etc.
Until you add this kind of validation I would copy the files into a work directory and process them there first to avoid any unfortunate mishaps or lost data.
Hope it is usefull.........
