I want to create the tar file on another server. When I execute this command it works, but when I put this command in my shell script it returns an error.

tar cvzf - prod_test.txt| ssh [email protected] "cat > prod_test5.tar.gz"

tar: -: Cannot stat: No such file or directory tar: prod_test.txt|: Cannot stat: No such file or directory tar: ssh: Cannot stat: No such file or directory tar: [email protected]: Cannot stat: No such file or directory tar: "cat: Cannot stat: No such file or directory tar: >: Cannot stat: No such file or directory tar: prod_test4.tar.gz": Cannot stat: No such file or directory v ÷Om7 7Þ'(tar:

#!/bin/sh
dy=`date +%a`
bk='/d01/backup'

Transfer Command

trans_oracle='tar cvzf -  prod_test.txt| ssh [email protected] "cat >  prod_test4.tar.gz"'

Delete Command

del_oracle='rm -f '$bk'/'$dy'_apps_indus_prod.tar.gz'
echo '****** Start Time ******' >> bk'/'$dy'_transfer_apps_bk_net.log'
date >> $bk'/'$dy'_transfer_apps_bk_net.log'
printf '\n' >> $bk'/'$dy'_transfer_apps_bk_net.log'

--#Transfer Backup
$trans_oracle
--#Delete Backup
#$del_oracle

echo '******  End Time  ******' >> $bk'/'$dy'_transfer_apps_bk_net.log'
date >> $bk'/'$dy'_transfer_apps_bk_net.log'

printf '\n' >> $bk'/'$dy'_transfer_apps_backuplog.log'
printf '\n' >> $bk'/'$dy'_transfer_apps_backuplog.log'

error

The code:

#!/bin/sh
dy=`date +%a`
bk='/d01/backup'

#Transfer Command 
trans_oracle='tar cvzf -  prod_test.txt| ssh [email protected] "cat >  prod_test4.tar.gz"'

date >> $bk'/'$dy'_transfer_apps_bk_net.log'
printf '\n' >> $bk'/'$dy'_transfer_apps_bk_net.log'

#Transfer Backup
$trans_oracle
#Delete Backup
#$del_oracle

echo '******  End Time  ******' >> $bk'/'$dy'_transfer_apps_bk_net.log'

printf '\n' >> $bk'/'$dy'_transfer_apps_backuplog.log'
printf '\n' >> $bk'/'$dy'_transfer_apps_backuplog.log'

  • Welcome to unix.se! Please post the error message. When you do not want to locally create a file with tar, you can drop the f option and -: tar cvz prod_test.txt| ssh [email protected] "cat > prod_test5.tar.gz". Both versions worked for me. Commented Feb 15, 2017 at 6:46

    Then please post the code from your script. Do you use bash? Did you try a space between prod_test.txt and pipe? Commented Feb 15, 2017 at 6:59

    @daniel not every version of tar defaults to stdout. It's better to be explicit and keep the -f - unless you can be absolutely sure if the default setting. Commented Feb 15, 2017 at 9:01

Reset to default

To show the issue you are getting a small testcase will suffice:

Individually this runs fine: 

ls; pwd

then we do this

cmd='ls ; pwd'

Now $cmd will give the error the files named ';' and 'pwd' are missing.

This is where precisely the "eval" command comes in when you want to give the shell another go:

eval "$cmd"

runs successfully as if you had given it at the command line.

So instead of $trans_oracle give it as: eval "$trans_oracle"

  • I have done this, actually the problem now is that it is showing errors tar: -: Cannot stat: No such file or directory prod_test.txt tar: Error exit delayed from previous errors Commented Feb 16, 2017 at 5:39
  • but even then it is creating the tar file on my target server Commented Feb 16, 2017 at 5:39
  • This error indicates you are not using the -f option in tar. Give: tar cvzf - prod_test.txt | .... Commented Feb 16, 2017 at 6:23

    finally this commnad works tar -cz prod_test.txt | ssh [email protected] "cat > /d01/prod_bk_net/PROD_TEST.tar.gz"' but now i want to replace prod_text.txt with a directory Commented Feb 16, 2017 at 11:04
