[Gambas-user] Hours of strugglin with EXEC and SHELL

[M0E Lnx]

The first gambas application that I wrote uses SHELL a lot... and I
came to find out that in gambas, the cd command wont do anything...
Say for instance, you need to first cd to /tmp and then run ls -al.
This WILL NOT WORK

PUBLIC SUB cdTEST()
SHELL "cd /tmp"
SHELL "ls -al"
END
In this case, when gambas executes the second command, it will return
the output of "ls" IN THE PROJECT'S DIRECTORY... not in "/tmp" as you
told it to in the first line

so, to accomplish this, you can use the bash concatenators (is that a
word)?? and write one-liners

PUBLIC SUB cdTEST()
SHELL "cd /tmp && ls -al" FOR READ
END
That should work
