I have these files, [processName.DateTime.out]
/stev/log: ls -al

And my script moves some files to archive folder if it is modified before 7 days.
sfind . -type f -mtime +7 -name "/stev/log" | while read FNAME
do
echo " moving file: " ${FNAME} >> /stev/archive/archiveLog.log
PCMD="mv ${FNAME} /stev/archive}"
echo "PCMD=${PCMD}" >> /stev/archive/archiveLog.log
eval "${PCMD}" >> /stev/archive/archiveLog.log
echo "" >> /stev/archive/archiveLog.log
done
this script will list below files then move them to the archive folder [Current date: Feb 5]
-rw-rw-r-- 1 user.stev user 4096 Jan 21 23:59 AAA01.202002010000.out
-rw-rw-r-- 1 user.stev user 4096 Jan 22 23:59 AAA01.202002020000.out

-rw-rw-r-- 1 user.stev user 4096 Jan 23 23:59 TEST03.202002030000.out
But the thing is, I have to remain the last files for each process.
For example) I can move belows files
-rw-rw-r-- 1 user.stev user 4096 Jan 21 23:59 AAA01.202002010000.out
-rw-rw-r-- 1 user.stev user 4096 Jan 22 23:59 AAA01.202002020000.out
-rw-rw-r-- 1 user.stev user 4096 Jan 21 23:59 TEST03.202002010000.out
-rw-rw-r-- 1 user.stev user 4096 Jan 22 23:59 TEST03.202002020000.out
but I should remain belows files (It doesn't matter how many days ago, for the last file for each process has to be remained.)
-rw-rw-r-- 1 user.stev user 4096 Jan 23 23:59 AAA01.202002030000.out
-rw-rw-r-- 1 user.stev user 4096 Jan 23 23:59 TEST03.202002030000.out
Is there any good idea for this problems??
Think in bash as in "streams" - something goes in, something goes out.
# find all files
find /stev/log -type f -mtime +7 |
# extract the part before dot
cut -d. -f1 |
# for each process
# could be transformed into `xargs sh -c '...' --` for speed
while IFS= read -r process; do
# all files with this process
find /stev/log -type f -mtime +7 -name "$process*" |
# sort numerically second field behind dot
sort -t. -n -k2 |
# remove last file, because we don't want to move it
# maybe you need to remove first line, then just sort -r, check it
head -n -1
done |
# mv each file into /stev/archive
xargs -d$'\n' -I{} mv -v {} "/stev/archive" >> /stev/archive/archiveLog.log
Pass -t option to xargs to debug it.
