Shell Programming and Scripting

Hi,

I have a question regarding finding free space on the disk of a solaris machine.

Many mount points are available in my machine. Right now i am using
df -b option to get the free disk space available.

I have an assignment to check free space on the disk.
I pass the directory as a parameter to my shell script. My shell script should read the parameter and check wether there is a sufficient space in the directory.

my inputs can be any of the follwing

/opt/Agent
/var/tmp
/var/opt/Agent
/Agent

I execued my command like this.

sh checkspace.sh /var/tmp

when the above command is executed i am getting correct result because /var/tmp exists on the machine.

if i specify sh checkspace.sh /Agent
the program halts with an error saying

block device not found.

this is because the directory is not existing.


can any one please give a solution to find free disk space when inputs /Agent and /opt/Agent are specified . the code should be same for both inputs.(should also remember /Agent is not an existing directory)


Thanks in advance

Did you check if directory exist first ?

The input is given as /Agent even if directory is not existing..
but it should still check for size
