File Size Position

Definition

Specifies the left-most position in the listing line that represents the size of the file. Even though for some operating systems the value shown might not truly reflect the file size, this position is still important in ascertaining that the line contains a valid file name.

Required Values

A non-negative integer. For Fixed list line format, the position value is the column number (starting with one (1) on the far left). For Blank Delimited, this value represents the field number (starting with one (1) on the far left). If the LIST line does not have a size field, set this parameter to zero (0).

Example

       -rw-r--r--   1 ed        usr           110 Apr 15 13:33 aaa
