I am trying to create a script that will run continuously until the out of a
command reaches a specific point.
I have a command called showOutput and all it does it output the progress of
running job, i want to create a script or a command that will process this
output and do something else once it sees the job has gotten to a specific
point. What I have come up with so far is something like this:
#this will give me only the 1 specific line i am waiting to see
showOutput | grep "condition"
#if i use this in an if statement or a loop like this:
until [ $( showOutput | grep "condition" ) ] do sleep(60); done
#run other command here
but i think because showOutput does not have an eof things dont work right
if anyone can help that would be greatly appreciated
Assuming your output is line-delimited, it sounds like you want
something like this:
processOutput() { # pipe output to this function
local l
while read l ; do
echo "$l" | grep "condition" &>/dev/null && break
doSomething1
done
while read l ; do
doSomething2
done
}
