Hi
Please can you help me in writing a script to find files on a specific directory, and of extension "tap" but only of the month of september, gzip and move them to another directory.
Your help will be appreciated.
Yes...
What have you done so far?
Why don't you move the files first then gzip all of them using * ?
I think the issue is identifying just the files from September:
#! /bin/ksh
BEGIN=$(mktemp)
END=$(mktemp)
trap "rm -f ${BEGIN} ${END}" EXIT
touch --date='09/01' $BEGIN
touch --date='10/01' $END
find "${SOURCEDIR}" -maxdepth 1 -type f -name '*.tap' -newer $BEGIN ! -newer $END -print \
| while read file; do
echo "${file}"
gzip -9 "${file}"
mv "${file}.gz" "${DESTDIR}"
done
rm $BEGIN $END
Hi
VBE:
I can move the files them gzip them, but I found something else that puzle me, look:
itc01[132]/data/ICTPRD/bmd1/rating/processed #find . -type f \( -name "*.tap" \) -exec ls -lrt {} \; | head

Why is if I use find, I see only november files, but if I do ls -lrt *.tap I see september files???
LUDWIG:
You are right the issue is september only:
I am going to test your script , although I did not understand the "gzip -9" section. can you explain? if its possible
regards
Because if you run any command through -exec the files names are passed along one by one. So you're not doing ls -lrt *.tap , but
ls -lrt ./ICTCDMOZ01AGOUT0280620111102151703.tap
ls -lrt ./ICTCDMOZ01AGOUT0280820111102151708.tap
ls -lrt ./ICTCDMOZ01AGOUT0281020111102151713.tap
ls -lrt ./ICTCDMOZ01AGOUT0280920111102151711.tap
ls -lrt ./ICTCDMOZ01AGOUT0281120111102151716.tap

You're using head , so you're only showing part of the output. Both commands will be returning all the files, but not necessarily in the same order (the ordering options on -exec ls won't apply to find, since it's processing files 1 at a time).

If you want those Sep files why dont you use
ll *.tap |grep " Sep "
If you are happy with what you see, then :
mv $(ll *.tap | grep " Sep " |awk '{print $9}') newDest/.

Your post was spot ON, Thank you very much
If you take a moment to look at the man gzip (linux) manual page, the -9 option (aka --best) is for maximum compression.
