On linux use the code from posting #4

Yes the two commands can be combined into a script perhaps something like this:

Code:
#!/bin/sh
#
# rm_list.sh
#
# Usage:  rm_list.sh list_file error_file  removed_file
#
if [ $# -ne 3 ]
then
   echo "Usage:"
   echo "   rm_list.sh list_file error_file removed_file"
   exit 1
fi
 
LIST=$1
ERR=$2
REM=$3
 
if ! [ -f $LIST ]
then
    echo "List file $LIST not found"
    exit 2
fi
 
xargs rm < $LIST 2> $ERR
nawk -F: 'NR==FNR{d[$1]++;next} !($0 in d)' $ERR $LIST > $REM

Thank you for the requested script and everything is working as expected. But i am getting below exception when running the script.

Code:
./rm_list.sh list_file error_file  removed_file
./rm_list.sh: !: not found

Please advise.

Thanks

Check for typos/misalignments somewhere around this code:

Code:
if ! [ -f $LIST ]
then
    echo "List file $LIST not found"
    exit 2
fi

I suspect you missed a space or two somewhere.

I am seeing this error in solaris but not on linux.

Odd. I think that's supposed to be valid syntax, but Solaris does have a really old and noncompliant shell...

Try putting the ! inside the [ ]

Code:
if [ ! -f $LIST ]

I have a similar type of files that needs to be removed from the below directory and sub-directory

Code:
cd /photos

find . -name "*12345678*" -ls
156040   58 -rw-r--r--   1 nobody   nobody      58389 Jul 27  2011 ./12345678.jpg
703506    2 -rw-r--r--   1 nobody   nobody       1309 Jul 27  2011 ./thumbnail/12345678-tn.jpg

So by providing the unique content in both files into a input file (i.e) 12345678 , how can we add a line to this script to take care of this operation. There are more than 100k records in the photos directory and as well as thumbnail directory which is the sub directory under photos.

Bottom line i only want to provide 8 digit number and that should delete the files under photos directory and its sub directory (i.e) thumbnails


Thanks

That would have been nice to know three pages ago...

Code:
while read ID
do
        echo "${ID}.jpg"
        echo "thumbnail/${ID}-tn.jpg"
done < inputfile | xargs 2> errlog
