Yes, that. Because you can't nest quotes inside quotes in a shell script and expect the shell to understand it later. You asked the shell for a literal quote, and you got a literal quote, and it's not going away without a lot of effort and ugly horrid things like eval.
When you try and split it again, you won't get /path/to/fakeCommand-poption with spaces. You'll get
The thing is with this, is that the "command" that the user will input will simply be put into a txt/cfg file as basically a literal string.
I've already had this implemented but was trying to fix up my REGEX a little more... The script inserts the "command" as-is into
the *.cfg file without any issues (*with any "options" that have quotes around them (due to having spaces) are still present
after appending) and I am able to execute the command with all options present in the config file...
Though what your saying, I have no doubt that it's true, really won't affect me for my purposes. Since basically all I'm
really doing is appending a single line (string) into a "text" file.
For Example:
Code:
localhost:/usr/local/nagios/bin # ./checkNRPE add "command[check_testCMD]=/usr/local/nagios/libexec/check_process -w 50 -c 75 -p '/bin/dbus-daemon --system' -t cpu" comment "This is a Comment for the Command with Alias=check_testCMD"
*The Command was added Successfully to the nrpe_local.cfg File!
localhost:/usr/local/nagios/bin # cat ../etc/nrpe_local.cfg
### NRPE's Local Config File:
### ILLEGAL CHARACTERS (*separated by whitespace) --> | ` & > < ' \ " [ ] { } ;
# The Check Command's Alias' CANNOT contain any of the above characters...
command[check_users]=/usr/local/nagios/libexec/check_users -w 5 -c 10
#command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
#command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/hda1
command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z
command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200
# Disk Space - Command is for checking Free/Used Disk Space for the Root Partition
command[check_rootPartition]=/usr/local/nagios/libexec/check_disk -w 10% -c 5% -
# This is a Comment for the Command with Alias=check_testCMD
command[check_testCMD]=/usr/local/nagios/libexec/check_process -w 50 -c 75 -p '/bin/dbus-daemon --system' -t cpu
localhost:/usr/local/nagios/bin #ps auxww | grep "[/]bin/dbus-daemon --system"
100 2357 0.0 0.0 2744 872 ? Ss Oct18 0:00 /bin/dbus-daemon --system
localhost:/usr/local/nagios/bin #
If you look at the last line in the cfg file above (from the 'cat' command), you can see that my "new" command is present in the cfg
file with all it's options accounted for (including one's that were quoted)... Also notice the PIDs match from the "ps" Command's
output (above) and from the new command's output from NRPE (below).
And executing the command remotely from the Nagios Server using NRPE:
Code:
NagiosSrv:/usr/local/nagios/libexec # ./check_nrpe -H 192.168.x.xxx -t 10 -c check_testCMD
OK: The CPU-Usage(%) is below ALL Warning Levels. PID(2357) CPU: 0.0%, RAM: 0.0%, CPU-TIME: 0 Min | CPU=0.0; Memory=0.0; PID=2357; CPU-Time=0; Virtual-Mem=2744; Physical-Mem=872
So, I think I'm ok with this the way it is for now....
Again, thank you guys for all your responses/suggestions it is MUCH appreciated!
