Hi folks,
I'm attaching an excerpt from a script I'm working at:
I'm getting following errors when running bash -xv for this script:
I guess there is something wrong about the syntax of the SED command, however I can't figure out which the issue is.
I'm getting the same errors when replacing the $(sed ...) with `sed ...`.
On the other hand when using sed without variables and only with single quotes I'm not getting any errors. Here's an example:
Thanks in advance for your help!
Cheers,
Liviu
I'm attaching an excerpt from a script I'm working at:
HTML-Code:
for i in {1..$line_nr_log}; do
tb=$(sed "$i"'q;d '"$log"); #line i of file log.txt (cotnaining the file/dir to be backed up) is read into variable $tb

All directories contained in the relative path are copied in the backup directory in order to preserve the original path; output of the command obtained in verbose mode is redirected to the temp_operations_log file

Try 'cp --help' for more information.I'm getting the same errors when replacing the $(sed ...) with `sed ...`.
On the other hand when using sed without variables and only with single quotes I'm not getting any errors. Here's an example:
HTML-Code:
central_backup_dir=`sed '1q;d' /home/test/bin/Backup_Scripts_Parameters`; #reading the path of the central backup directory, which is contained by the first line of the Backup_Scripts_Parameters file (this file contains certain parameters of the scripts fbackup.sh and dbackup.sh)Cheers,
