Syntax
Input parameters
String
Return values
printDirSize()
Checks the NFS status of the mounted file system and then gets the disk space of
the file system or its parent directory.
Purpose
This function first calls the NFScheck function to determine the NFS status of the
directory. If the status is true, it calls the getClosestExistingParentDir function to
return the directory or its parent directory, and then use the df command to get the
amount of free disk space. It finally calls the formatSizeDisplay function to round
the value to decimal points.
Syntax
printDirSize dirpath
Input parameters
String $dirpath
Contains the path to the directory for which to get the free disk space.
Return values
Integer dsize
Returns the amount of free disk space to within two decimal points.
String "NFS_NOT_AVAILABLE"
Returns that the mounted filesystem is not available.
