I am running a bash script that creates a log file for the execution of the command
I use the following
Command1 >> log_file Command2 >> log_file This only sends the standard output and not the standard error which appears on the terminal.
493
1 "Standard output" output file descriptor. The expression 2>&1 copies file descriptor 1 to location 2 , so any output written to 2 ("standard error") in the execution environment goes to the same file originally described by 1 ("standard output").
Discussion. &> or >& is a shortcut that simply sends both STDOUT and STDERR to the same place—exactly what we want to do.
If you want to log to the same file:
command1 >> log_file 2>&1 If you want different files:
command1 >> log_file 2>> err_file If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
