My (new)problem is to find substring which contain single quote within the file. And to print to the screen what is to be being done.

Making some try, I can print the variable CMD which show on screen the good code to be executed:

Code:
.......
.......
.......
echo "COMMAND : $CMD"

Show :
Code:
COMMAND : CNT=$(  grep -c -e  "Non-option program arguments: 'nxclient'" -e   "Checking whether to refresh metadata for zypper_local"  -e  "Selecting 'nxclient-3.5.0-7.x86_64' from repository 'zypper_local' for installation."  /tmp/nxclient_install_log.txt )

Which is correct; and should give CNT=3 which is correct.
But when I try to execute $CMD I get this error :
Code:
/root/bin/freenx_install_server_function: line 102: CNT=$(: command not found

How to execute $CMD with success.
