I have a script with several options and during testing I found that the \? option does not handle options without dashes as I would expect. Then I run the script with any option that does not include a dash, it runs the script when I would expect \? to catch it and error.
I've tried this with OPTERR=0 and OPTERR=1 and don't get any errors. Do I need to write a function to catch options without dashes? Seems that would be something getopts should catch.
Hi all,
I am parsing command line options using getopts.
The problem is that mandatory argument options following ":" is taking next option as argument if it is not followed by any argument.
Below is the script:
while getopts :hd:t:s:l:p:f: opt
do
case "$opt" in

Hello everyone,
Is it possible to use getopts and also receive arguments without option flags?
e.g. myscript arg1 arg2 -a arg3 -b arg4
If so, how do you stop getopts from exiting as soon as it detects the non-option arguments? (2 Replies)

Hello,
Does getopts have some way of handling the use of an option that requires a parameter more than once on the command line.
e.g. mycmd -a john -a jane
I came up with a solution using arrays (shown below), but wonder if getopts has some other way of handling it. Other solutions... (2 Replies)

I use the "getopts" ksh built-in to handle command-line options, and I'm looking for a clean/standard way to "unset" an option on the command line. I don't know if this is a technical question about getopts or more of a style/standards question. Anyway, I understand that getopts processes its... (4 Replies)

Well, guys I saw a question about GOTO for Python.
So this gave me the inspiration to attempt a GOTO function for 'dash', (bash and ksh too).
Machine: MBP OSX 10.14.3, default bash terminal, calling '#!/usr/local/bin/dash'...
This is purely a fun project to see if it is possible in PURE... (3 Replies)

echo
echo(1B) SunOS/BSD Compatibility Package Commands echo(1B)NAME
echo - echo arguments to standard output
SYNOPSIS
/usr/ucb/echo [-n] [argument]
DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output.
echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi-
ronment variables.
For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:
o echo your current-working-directory's full pathname
o pipe the output through tr to translate the path's embedded slash-characters into space-characters
o pipe that output through wc -w for a count of the names in your path.
example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"
See tr(1) and wc(1) for their functionality.
The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if
the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape
characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's
echo() also understands a as the audible bell character; however, these commands do not have an -n option.
OPTIONS -n Do not add the NEWLINE to the output.
