i don't understand why i do not get an output.
when i execute these commands in the shell, they work perfectly but when i assign them a variable and do echo to print the variables, no output when i execute the shell. the shell waits for command to end.

Based on the number of volumes/files on your server, find can take a substantial amount of time to search something from /.
Time one of the find commands separately and multiply that time by 3. That is the amount of time your script will probably take before giving any output at all.
This User Gave Thanks to a_programmer For This Post:
The commands as posted will not produce any output. They will just put concatonated values into the three environment variables $a $b $c . There is a limited size to an environment variable.
Also, there is no point to the "-inum +1" cause.
What are you trying to do, and what do you want the output to look like?
hey methyl,
trying to look for regular files, with one or more inodes, modified within the last 30 days.
variable a would display time last accessed, b would display time last modified and c would display full path of the file.
could i have done without the-inum +1? thanks.
It's a waste of time to traverse the file tree three times when you only need to do it once. You didn't say which flavour of Unix, but if you have a stat command installed, something like this produces 5 columns of output for each file that matches your find criteria and only one pass across the filesystem (in terms of find) is needed. Output, left to right, is date/time of last access, date/time of last modificaton, and file name.
The sed just strips decimals from the time and the timezone offset.
Depending on what tools you have installed, the -E option to sed might need to be -R. On a FreeBSD system the stat command will be something like this:
As for whether or not to use -inum...
The way I read the man page for find, inum is used to match a specific inum. As a file can only have one inum using a +1 construct makes no sense (at least not to me).
