I have a bash upload script which looks like this -
if [ $# -lt 2 ]
then
echo usage: $0 /path/to/mvn /path/to/libs [procs] [groupId]
fi
MVN_EXE=$1
LIB_DIR=$2
PROCS=10
GROUPID=$4:-'default'
if [ $# -gt 2 ]
then
PROCS=$3
fi
I want the GROUPID to be the 4th arg or to be set automatically to 'default'. Could I be advised on the correct syntax for this? A google search has given me this so far. Would I then need to add an additional if search along the lines of -
if [$# -gt 3]
then
PROCS=$3
GROUPID=$4
fi
or just replace the original if statement with the new version?
Thanks

You just forgot the curly braces. You can use them to avoid the final if statement too:
if [ $# -lt 2 ]
then
echo usage: $0 /path/to/mvn /path/to/libs [procs] [groupId]
fi
MVN_EXE=$1
LIB_DIR=$2
PROCS=${3:-10}
GROUPID=${4:-'default'}
