[Gambas-user] Re gular Expression Help

[M0E Lnx]

Throw it into an array..

DIM sList as string[]
dim sStr as string
DIM i as integer
dim sOneDev as string

SHELL "ls -m /dev | grep [sh]d[a-z]" to sStr
sList = Split(sStr, ",")

FOR i = 0 to sList.Count - 1
sOneDev = left(trim(sList[i]), 3)
Print sOneDev
Next

This first, produce a list separated by commas, then use a gambas
array to separate the array into separate strings. After that, you run
the FOR Loop to trim out the text you need

Unless I'm not understanding this right.
