linux - bash scripting: search Java STDOUT for a variable -

when run mytest.jar, outputs alot of information in stdout (not in file) , trying read/search file specific string put variable in bash script.

java stdout:

line 1 info............   line 2 info...........   ....   ...  successful    (either 'successful' or 'failed')

how search for, in bash, last line in stdout or ('successful' or 'failed') without redirecting stdout file?

thanks in advance

this not way of checking success or failure.

you should instead rewrite mytest.jar use system.exit(0) on success , system.exit(1) (or higher) on error. if program written, this.

you can check success or failure in bash using e.g.

if java -jar mytest.jar    echo "the command succeeded :d" else   echo "the command failed :(" fi

all unix programs work way, , should make sure mytest.jar no exception.
