The fstab (or file systems table) file is a system configuration file commonly found at /etc/fstab on Unix and Unix-like computer systems. In Linux, it is part of the util-linux package. The fstab file typically lists all available disk partitions and other types of file systems and data sources that may not necessarily be disk-based, and indicates how they are to be initialized or otherwise

Se hela listan på pcforalla.idg.se ls >/dev/null 2>&1 ls 2>&1 >/dev/null Indeed, in the later case, file descriptor 2 is set to the current address of file descriptor ``1 (which is stdout at this very moment), and then the file descriptor 1 is redirected to /dev/null. File descriptor 2 is still redirected to stdout, no matter what happens to file descriptor 1.

And by using command: nohup MY_COMMAND > /dev/null 2>&1 & echo $! we can return the pid of the process. This small class is made so you can keep in track of your created processes ( meaning start/stop/status ). You may use i

The Year 2038 problem (also called Y2038, Epochalypse, Y2k38, or Unix Y2K) relates to representing time in many digital systems as the number of seconds passed since 00:00:00 UTC on 1 January 1970 and storing it as a signed 32-bit integer.

ls 2>&1 means temporarily connecting the stderr of the ls command to the same " resource" as the shell's stdout. By convention, a command reads its input from fd 0

So when you use 2>&1 you are basically saying “Redirect the stderr to the same place we are redirecting the stdout ”. And that’s why we can do something like this to redirect both stdout and stderr to the same place: Your colleague is correct. The 2>&1 just redirects Channel 2 (Standard Error) and Channel 1 (Standard Output) to the same place which in this context is Channel 1 (Standard Output), and thence your log file. If all output from a cron is redirected to a file, it will not generate an email of … 2>&1 merges stderr with stdout, which can be useful if, for example, you want to pipe stderr text. So, for example, if you want to see if a program prints a certain stderr message, but don't want your screen filled with (presumably) unimportant garbage, you could do something like program 2>&1 | grep crashed , which will search the stdout and stderr from a program called "program" for the word 2) The accepted answer is wrong and misleading. The correct answer is "there is no default meaning for the exit codes (beyond 0 = success); you as script developer define the semantics". 3) If you made that script, why did you add the exit commands (all of which are logically superfluous or could collapse to "exit 1" since you use if-else anyway).
