ksh -> echo ${var:-n/a}

[w5000]

is it possible to get working it with variable instead of plane/written "n/a" ?

so,
v="n/a"

and then:

echo ${var:-[red]$v[/red]}

(but of course working one ;-) )

Hi

Do you have a version restriction too ? That works for me in MKsh :

[blue]master[/blue] # v="n/a"

[blue]master[/blue] # echo ${var:-$v}
n/a

[blue]master[/blue] # var=wtf

[blue]master[/blue] # echo ${var:-$v}
wtf

$ ddd=bbb
$ echo ${SVSA:-$ddd}
bbb
$ ddd=n/a
$ echo ${SVSA:-$ddd}
n/a
$ echo ${SVSA:-$ddd}
n/a
