Confused with the usage of one variable usage

Shell Programming and Scripting

Hi All

I am not able to understand the usage of d# in the below variable declaration.

FILE_LOC contains the directory path

And also help me to know about what will be saved in the variable j.

Thanks!!!

j=${d#${FILE_LOC}/}

see below this might help

ok.. this is an excerpt from man ksh
           ${parameter#pattern}
           ${parameter##pattern}
                               If the shell pattern matches the beginning of
                               the value of parameter, the value of this
                               substitution is the value of the parameter
                               with the matched portion deleted; otherwise
                               the value of this parameter substituted.  In
                               the former case, the smallest matching
                               pattern is deleted; in the latter case, the
                               largest matching pattern is deleted


basically FILE_LOC is a location and d is also a location and if ur pattern of location matches with each other. then only the portion (directory in the last that is not being matched is shown)
