Question Delete old files but with exclusion with file list
Hello Can you please help and check what im missing on script below
the goal is to delete the old files more than 7 days old but not the excluded file list inside excluded.dat file

Code:
#!/bin/sh
EXCLUDE=/path/to/exclude/exclude.dat
FIND=/bin/find
for xfile in '(read $EXCLUDE)'
do
$FIND /path/to/fordelete -type f -mtime +7 | 'grep -i $xfile' | xargs rm-rf
done

Strangely this script contains many errors which are not in your previous posts.
What is the format of the file exclude.dat ? The script is easier if exclude.dat contains full path names exactly as would be produced by find.
What Operating System are you using? The syntax for "find" "grep" and shell varies.

Try,

Code:
$ find /path/to/fordelete -type f -mtime +7 | grep -v "$(cat /path/to/exclude/exclude.dat)" | xargs rm -f

@agn
I don't think that your "grep -v" works if file "exclude.dat" contains more than one line.

@angst_nu
The script becomes too complex to write to commerical quality if the exclude.dat file does not contain full path names. One can then use "grep -x" for an exact match to avoid accidental matches (e.g accidentally matching "foo" in "foobar").

Unless this is coursework it could be worth changing the design to suite the tools.

@agn does not work for me.


Code:
$ find /path/to/fordelete -type f -mtime +7 | grep -v "$(cat /path/to/exclude/exclude.dat)" | xargs rm -f

grep -x is not supported on sun solaris 10?

grep options
grep -hblcnsviw

Solaris 10
/usr/xpg4/bin/grep
You may be able to use the "-F" option with "-f pattern_file" to process your list. There was a post on this board recently using that method.
