hi.got a couple of test bash scripts. dog.sh, cat.sh each script runs the underlying php in an endless loop. I'm trying to figure out how to run the scripts in parallel, from the same parent shell script. something like: test.sh where dog.sh would be : -------------------------------- while true do pgrep dog if [ $? -ne 0 ] then /dog.php fi sleep 5 done my current tests, run dog.sh, which runs the dog.php ... but the test never gets to run cat.sh thoughts/comments... thanks
Hey Bruce, Do you mean to run these subprograms in parallel or in series? cat.sh #! /bin/bash CAT=0 until [ $CAT -eq 10 ] do echo "Inside a dog it's too dark to read. $CAT" CAT=$[$CAT + 1] sleep 2 done dog.sh #! /bin/bash DOG=0 until [ $DOG -eq 10 ] do echo "Next to a dog a book is man's best friend. $DOG" DOG=$[$DOG + 1] sleep 2 done test.sh #! /bin/sh /home/mlapier/test/dog.sh 1>&2 & /home/mlapier/test/cat.sh 1>&2 & [mlapier@mushroom test]$ ./test.sh [mlapier@mushroom test]$ Next to a dog a book is man's best friend. 0 Inside a dog it's too dark to read. 0 Next to a dog a book is man's best friend. 1 Inside a dog it's too dark to read. 1 Next to a dog a book is man's best friend. 2 Inside a dog it's too dark to read. 2 Next to a dog a book is man's best friend. 3 Inside a dog it's too dark to read. 3 Next to a dog a book is man's best friend. 4 Inside a dog it's too dark to read. 4 Next to a dog a book is man's best friend. 5 Inside a dog it's too dark to read. 5 Next to a dog a book is man's best friend. 6 Inside a dog it's too dark to read. 6 Next to a dog a book is man's best friend. 7 Inside a dog it's too dark to read. 7 Next to a dog a book is man's best friend. 8 Inside a dog it's too dark to read. 8 Next to a dog a book is man's best friend. 9 Inside a dog it's too dark to read. 9 -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
