[gradsusr] get output from shell command

[Becker, Bernd]

Hello,

how do I get the output from shell command "date"
into the grads shell?

'!date'
res  = result
say rc    res
res=sublin(rc,2)
say rc    res
say subwrd(res   ,2)

doesn't do it.

Te following does, but with caveats:
I got this far: 

'!date -d 'fxdate' +%b > ./erp2' 
record2=read('./erp2')
mon=sublin(record2,2)

but it is unsave if multiple processes run in parallel and 
overwrite erp2. Not good enough.

many thanks!

Bernd.
