Hi!
----
The following script tries to use two functions which each seperately
use "getopts" for argument parsing:
-- snip --
function modify_target_param2
{
usage=":"
usage="${usage}B:(bi-directional-authentication)"
while getopts "${usage}" option
do
case ${option} in
"B")
bi="${OPTARG}"
;;
"?")
(( OPTIND = ${OPTIND} + 1 ))
;;
esac
done
}
function modify_target_param
{
set -o xtrace
usage=":"
usage="${usage}B:(bi-directional-authentication)"
while getopts "${usage}" option
do
case ${option} in
"B")
bi="${OPTARG}"
;;
"?")
(( OPTIND = ${OPTIND} + 1 ))
;;
esac
${mod} && modify_target_param2 -B enable target
done
return 0
}
mod=$1
[[ ${mod} == ~(Elr)(true|false) ]] || exit 10
modify_target_param -B enable target
print "#done"
exit 0
-- snip --
Running this script with ast-ksh.2009-06-22 results in output which
doesn't look right:
1. Running it with argument "false" returns the expected output:
-- snip --
$ ksh93 getoptste.sh
false
+ usage=:
+ usage=':B:(bi-directional-authentication)'
+ getopts ':B:(bi-directional-authentication)' option
+ bi=enable
+ false
+ getopts ':B:(bi-directional-authentication)' option
+ return 0
#done
-- snip --
2. If I run it with argument "true" I get this output:
-- snip --
$ ksh93 getoptste.sh
true
+ usage=:
+ usage=':B:(bi-directional-authentication)'
+ getopts ':B:(bi-directional-authentication)' option
+ bi=enable
+ true
+ modify_target_param2 -B enable target
#done
-- snip --
Why is the "getopts" parsing of function "modify_target_param2"
affecting the parsing in function "modify_target_param" (AFAIK I would
expect that they can each have their independent "getopts" parsing) ?
And why is the "return 0" statement in function "modify_target_param"
not being called ?

Bye,
