Testing standard output and exit statuses from commands in a pipe
Hello! I'd like to pipe the output from a command, say A, to another command, say B, then check if both commands completed successfully (i.e.with exist status 0) and, if so, compare the standard output from command B to some string. How can I do this in a bash script? Regards, Angel Tsankov

PIPESTATUS
An array variable (see Arrays below) containing a list of exit
status values from the processes in the most-recently-executed
foreground pipeline (which may contain only a single command).

Ah, that makes it much trickier. You can't use PIPESTATUS when you're
capturing the output of a pipeline with a command substitution.
arc1:~$ x() { echo x; exit 1; }
arc1:~$ y() { echo y; exit 0; }
arc1:~$ x|y; echo "${pipestat...@]}"
y
1 0
arc1:~$ q=$(x|y); echo "${pipestat...@]}"
0
In this case, you will need either a temporary file, or a named pipe.
