[SOLVED] tar + split + output

raguetrenaud · 07-13-2015, 07:22 AM

Hello,

I have this command:

$TAR -cvf - $SOURCEDIR $EXCLUDEDIR | split --bytes=1999m - $BACKUP_DEVICE 1>/usr/backup/backuped_files.lst

this part is working as expected:

$TAR -cvf - $SOURCEDIR $EXCLUDEDIR | split --bytes=1999m - $BACKUP_DEVICE

this part is not working:

1>/usr/backup/backuped_files.lst

My purpose is to catch the backuped files in backuped_files.lst (screen output without errors)
Can you help me?

Regards,

Renaud

Because of the pipe, the redirect is only catching output of the second command. Put the redirect before the pipe like this:

Code:

$TAR -cvf - $SOURCEDIR $EXCLUDEDIR 1>/usr/backup/backuped_files.lst | split --bytes=1999m - $BACKUP_DEVICE

You can use 'tee' for strange redirections if you want to read up on it.

i tested it:

redhat #tar cvf - /usr/backup/ --exclude=/usr/backup/logs 1>/usr/backuped_files.lst | split --bytes=1m - /usr/tartestoutput.tar.

the backuped_files.lst file is 100M and contains logs from 10 july 2015
no tar created

tar cvf - /usr/backup/ --exclude=/usr/backup/logs | split --bytes=1m - /usr/tartestoutput.tar. (worked as expected)

hello,

i found a workaround (not clean but working…):

i inserted tags (tar start and tar end)in my log file and i used /bin/sed to extract tar logs from it.

extract tar logs from backup.log to backuped_files.lst

Code:

sed -n '/^tar start/,/^tar end/p' backup.log > backuped_files.lst

remove tar logs from backup.log

Code:

sed '/^tar start/,/^tar end/d' backup.log > backup.log

Regards,

Renaud
