Iterate twice on bash scripts arguments using getoptex -


i'm writing bash script needs long arguments, --argument , not letters -a. there function called getoptex can found here can handle this.

the thing is, project specific modular. single script called, , need iterate on arguments find option tell me source script, has specific options , needs parse arguments again. there around 5 differents subscripts, each ones whith own options.

but first iteration on $@ seems erase every arguments , options (but leaves arguments without options), can't parse twice !

i'm giving code sample see i've done.

#!/bin/bash  source ./getopt.sh  echo "$@"  while getoptex "a; b;" "$@"     if [ "$optopt" = "a" ];         echo "a"     elif [ "$optopt" = "b" ];         echo "b"     fi done shift $[optind-1] arg in "$@"     echo "$arg" done  optind=1 unset optofs  echo "$@"  while getoptex "a; b;" "$@"     if [ "$optopt" = "a" ];         echo "a"     elif [ "$optopt" = "b" ];         echo "b"     fi done shift $[optind-1] arg in "$@"     echo "$arg" done

but never parses second time... idea ?

leave out first call shift. usually, use remove arguments you've parsed, since want parse them twice, don't want remove after first pass.

by way, $[optind-1] obsolete; use $((optind-1)) instead.

java - How to specify maven bin in eclipse maven plugin? -

i have eclipse maven plugin coming on centos. how can execute maven command on linx like: mvn clean package [abigail@localhost ~]$ mvn bash: mvn: command not found how should specify path executable of maven plugin in eclipse? or have install maven seperately？ thanks. eclipse (m2e) have bundled central parts of maven inside eclipse plugin, why not detected, , not usable. investigation find correct way bootstrap it, have create launcher file manually. if want run maven outside of eclipse, far better off standalone version of maven. mvn command bootstrap maven runtime system correctly, , secondly, able use advice concerning use of maven. maven binaries quite stable, wouldn't need upgrade upgrade eclipse. you can subsequently switch eclipse use external installation if prefer.
