Shell Programming and Scripting

I have written a script that deletes files:

Requirement: i need to delete the files and to know how many files are deleted i.e the count of files and even i need to display when the started time of deletion and the ending time of deletion. I need to display these two times.

script:

Code:

export j
j=0
for i in `find /opt/CGEYScripts -name "core*" -print`
do echo $i
rm -f $i
j=j+1
done
echo `j'

error:
test1:integ>./Purging.sh
/opt/CGEYScripts/coredumps.ctl
/opt/CGEYScripts/cored
./Purging.sh[8]: j: not found

Can anyone modify the script that meets my requirement, please?

First, you have used a backquote instead of a dollar sign in the last line where you display the variable j, which is causing the last error.

Second, you should not use backquotes any more, they are outdated. Use "$(...)" instead.

Third, - only if you use ksh - use "print" instead of "echo", because "print" is a built-in while "echo" is an external command.

Fourth, you should not use "for"-loops to cycle through arbitrary lists, because they could become longer than what your shell could fathom. Use a pipeline instead:

Code:

typeset -i DeletedFiles=0
print - "Started purging at: $(date +'<your preferred format here>')"
find opt/CGEYScripts -name "core*" -print | while read filename ; do
     print - "Deleting: $filename"
     rm -f $filename
     (( DeletedFiles += 1 ))
done
print - "Finished purging at: $(date +'<your preferred format here>')"
print - "Deleted $DeletedFiles files."

For a fitting format string for "date" consult the manpage of "date".

I hope this helps.

Thanks a lot. It works wonderfully. However, i need to add something to this.

Desired Output:

want to display the output as:

Deleting from the <directory>
<<file1>>
<<file2>>
<<file3>>
;
;
;
<<filen>>

Looking forward...

Thanks in advance,
