Thread: simple default variable

i know not correct. want option variable default if option not given on command line.

code:

#!/bin/bash  foo2option=1 foo1 $(foo2 --foo2option $2 $1)

running script no option:

code:

$ ./script somefile

would run:

code:

foo1 $(foo2 --foo2option 1 somefile)

running script option:

code:

$ ./script somefile 2

would run:

code:

foo1 $(foo2 --foo2option 2 somefile)

have @ bash

code:

${parameter-default}, ${parameter:-default}

syntax - should - like

code:

#!/bin/bash  default=2  echo command $1 ${2:-$default}

will use 2nd command line argument $2 if set, , $default otherwise
