Hey, all!
Why is the "human readable" flag changing the behavior of du? And while I'm at it, can you make du only look at files, not directories. I often find myself wanting to find the largest file(s) in a dir or vol. Using 'find' itself, it seems you have to at least be able to guess the size of... (2 Replies)

getopt(1) General Commands Manual getopt(1)
NAME
getopt - Parses command line flags and arguments
SYNOPSIS
getopt format tokens
DESCRIPTION
The getopt command is used to parse a list of tokens using a format that specifies expected flags and arguments. A flag is a single ASCII
letter and, when followed by a : (colon), is expected to take a modifying argument that may or may not be separated from it by one or more
tabs or spaces. (You can include multi-byte characters in arguments, but not as flag letters.)
The getopt command completes processing when it has read all tokens or when it encounters the special token -- (double dash). It then out-
puts the processed flags, a --, and any remaining tokens.
If a token fails to match a flag, getopt writes a message to standard error.
NOTES
In the csh, use the following command to run getopt:
set argv=`getopt flag_string $*`
EXAMPLES
The following is an example of the use of getopt in a skeleton shell script to parse options:
#!/bin/sh # parse command line into arguments set -- `getopt a:bc $*` # check result of parsing if [ $? != 0 ] then
exit 1 fi while [ $1 != -- ] do
case $1 in
-a) # set up the -a flag
AFLG=1
AARG=$2
shift;;
-b) # set up the -b flag
BFLG=1;;
-c) # set up the -c flag
CFLG=1;;
esac
shift # next flag done shift # skip double dash # now do the work . . .
The following are all equivalent arguments to the script:
-a ARG -b -c -- A B C -a ARG -bc -- A B C -aARG -b -c -- A B C -b -c -a ARG -- A B C
