Need help for a Shell script to rename multiple files
Hi!
I need help to create a shell script to search inside a file and then copy a portion of the search result as the new file name.
Basically I was hacked over the weekend and the genius wipe out my drive from my server. I was able to recover alot of files, but biggest problem Is now the files have no name and make it impossible to sort.
I have found the filename inside the files themself and need to search for it and then rename the file with the results.
Approx 12 000 files to be done.
Here is a sample of the source of the files I'm talking about:
# assuming the files are all called file_ something
for fn in `ls file*`
do
# display first ten lines
head -10 $fn
# or, more of what you need
newnam=`head -10 $fn | grep "%%Title" | cut -d" " -f2"`
# now rename it
mv $fn $newnam
done
Illustrator 9-10-04003
Illustrator 9-10-04004
Illustrator 9-10-04005
Illustrator 9-10-04006
and so on

Reason: Code tags please...
# assuming the files are all called file_ something
for fn in `ls file*`
do
# display first ten lines
head -10 "$fn"
# or, more of what you need
newnam=`head -10 "$fn" | grep "%%Title" | cut -d" " -f2"`
# now rename it
mv "$fn" "$newnam"
done
root# for fn in `ls illustrator*`; do head -10 "$fn" newnam=`head -10 "$fn" | grep "%%Title" | cut -d" " -f2"` mv "$fn" "$newnam"; done
ls: illustrator*: No such file or directory
root# ls

I think both forms of the loops are choking because the whitespace in the file names. The shell uses the value of IFS to break apart fields, and this is usually a white space. Using a shell 'for' loop in the form of
Code:
for file in $( ls Illustrator* ) #modern form of: for file in `ls Illustrator*`
will break all the files names apart on white spaces (or more accurately on the values in $IFS). You will get the error of "[utility]: No such file or directory [file fragment]"
the other 'for' loop form of:
Code:
for file in '$( ls Illustrator* )' #or for file in "$( ls Illustrator* )"
also does not work because the shell loop returns a single monolithic paragraph with ALL the files names in it.
You can a) rename all the files with no white space, or b) use a form of loop that can use asciz strings for the loop, c) use Perl.
The general form of loop 'b' that can use ASCIZ strings in the loop is like this:
Code:
find [directory] -type f [-maxdepth X] -print0 | while read -d $'\0' file
do
#rename the files
done
Note the "-print0" and the "while read -d $'\0'". The first reads the file names and puts them in a string that is terminated by a ASCII NUL; the second sets a while loop that reads the list with NUL terminators...
