Re: How to execute shell command and store result to variable?

Because Informix uses the exit code on the run returning it will not return the number of files from wc. To accomplish this you need to create a script file like this: MCOUNT=`ls|wc -l` exit $MCOUNT in your 4gl program it should look something like this: LET run_txt="<script filename>" RUN run_txt RETURNING tot_file LET tot_file=tot_file/256 IF tot_file < 3 THEN ERROR "Incomplete files! Process aborted!" SLEEP 3 EXIT PROGRAM END IF this should accomplish what you need. Hope this helps. --- ,-, |~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| ======= ___|| | | ----- //_ || | CANNON EXPRESS | ---- ,-----'| ~ | | | -- |o-----|__ |--`======_______________________________======___| ~~~~~~~~ `-(*)--===~~~~~~(*)(*)| (*)(*)| ------- ------------------------------------------------------------------------- Joseph Cullipher |E-mail: joseph@cannonexpress.com PO Box 364 |opinions express are those of my own and Springdale, AR 72764 USA |don't necessarily reflect those of my company ------------------------------------------------------------------------- On Fri, 21 Mar 1997, EHLIM wrote: > > Hi Informix programmers, > > > Can I run a Unix shell command like " ls .... | wc -l " and store the result > into a variable for my program varification purpose.
