set variable value based on if string existing in output
I solved my issue by using the following code
Code:
#!/bin/bash
function GET_STATUS {
#values Active Passive Failed
ssh -a localhost '/home/user/fakecommand.sh'
}
STATE="unknown"
until [[ "$STATE" = "Failed" ]]
do
echo $STATE
sleep 5
STATUS=`GET_STATUS`
echo $STATUS | grep Active && STATE="Active"
echo $STATUS | grep Passive && STATE="Passive"
echo $STATUS | grep Failed && STATE="Failed"
done
bash script: I want to wait until the output from function contains certain values
Note: this function ssh's into a remote server runs a command and outputs data to standard out
Code:
function GET_STATUS {
ssh -a localhost '/home/user/fakecommand.sh'
}
Unfortunately the output from the remote command changes length in both line numbers and sometimes it has extra white space..
It looks something like this....
Running command.....
Code:
variable length:stuff i dont need1 stuff i dont need2 status stuff i dont need3
variable length:stuff that i dont need 1 stuff i dont need2 Active stuff i dont need3
I want to perform actions based on the value of the status column
There are only 3 values..... Active,Passive,Failed
I have written the following code, but i think it could be much better.
Code:
GET_STATUS | grep "Active" && STATE="Active" # I Set the variable first so that i dont have to wait for the sleep if it is already in Active
until [[ "$STATE" = "Active" ]]
do
echo "Running GET_STATUS" && sleep 1
GET_STATUS | grep "Active" && STATE="Active"
done
Can anyone think of a way i can set the the variable $STATE
Any heap would be greatly appreciated
Thanks
