The simple solution:
output=$(complex_command)
status=$?
if (( status == 0 )); then
: stuff with "$output"
fi
: more code
if (( status == 0 )); then
: stuff with "$output"
fi
Or more eleganter-ish
do_complex_command () {
# side effects: global variables
# store the output in $g_output and the status in $g_status
g_output=$(
command -args | commands | grep -q trigger_word
)
g_status=$?
}
complex_command_succeeded () {
test $g_status -eq 0
}
complex_command_output () {
echo "$g_output"
}
do_complex_command
if complex_command_succeeded; then
: stuff with "$(complex_command_output)"
fi
: more code
if complex_command_succeeded; then
: stuff with "$(complex_command_output)"
fi
Or
do_complex_command () {
# side effects: global variables
# store the output in $g_output and the status in $g_status
g_output=$(
command -args | commands
)
g_status=$?
}
complex_command_output () {
echo "$g_output"
}
complex_command_contains_keyword () {
complex_command_output | grep -q "$1"
}
if complex_command_contains_keyword "trigger_word"; then
: stuff with "$(complex_command_output)"
fi
