Re: RUN and the shell

> Q. Is there a way to force the RUN command to use sh? > An informix specific env setting perhaps? Yes. That happened to one of the guys here. What we did was to set SHELL environment variable to /bin/sh. 4GL's RUN uses SHELL variable to start up a shell. Another gotcha in the area is that for System V Rel 3 (dunno about BSD, and others) the total number of characters in your environment PLUS the command line can not exceed 5K bytes. This one had us scratching our heads for a while until we figured out what the problem was. This has a very big impact on Makefiles. > If not then I guess I'm stuck with setting SHELL prior to fglgo'ing > and restting it afterwards. Ah, just write a little teensy script: #!/bin/sh # kick off fglgo (bourne shell version) # set -a #export all variables automatically INFORMIXDIR=${INFORMIXDIR:-'/usr/informix'}SHELL=/bin/sh exec $INFORMIXDIR/bin/fglgo "$@" And your csh's SHELL wont be changed in any way. A child shell can not change any of his/her parent's environment variable. If your Unix system doesn't understand #!/bin/sh, then you can rewrite the script in csh. > Cheers, Ian. -- ------------------------------------------------------- | Paul T.
