are voted up and rise to the top How do I suppress error messages from cp? up vote 1 down vote favorite I am currently looking ways to suppress error command in Linux, in particular, the command cp. I do: root@ubuntu:~$ cp /srv/ftp/201*/wha*/*.jj ~/. cp: cannot stat `/srv/ftp/201*/wha*/*.jj': No such file or directory How do I suppress the error message that gets printed on the screen? I.e., I don't want to see solaris error messages this error message in my monitor. shell wildcards cp share|improve this question edited Apr 27 at 17:55 Anthon 47.5k1462125 asked Mar 23 '15 at 17:58 andy_ttse 5217 1 just FYI, best way to check for errors is exit codes. Piping STDERR to /dev/null is standard and will get rid of any visual indication of errors, but checking for a non zero return status will let you know if there was an error or not, at least that is how it is supposed to be... –Nathan McCoy Mar 23 '15 at 18:06 Your question is not clear. Do you want to hide all error messages from cp? Or do you want to have no error message if the wildcard doesn't match any files? Or some other criteria? –Gilles Mar 23 '15 at 23:18 add a comment| 4 Answers 4 active oldest votes up vote 7 down vote accepted To suppress error output in bash, append 2>/dev/null to the end of your command. This redirects filehandle 2 (STDERR) to /dev/null. There are similar constructs in other shells, though the specific construct may vary slightly. share|improve this answer answered Mar 23 '15 at 18:03 John 7,5181719 add a comment| up vote 2 down vote Redirect the error message (STDERR) to /dev/null: root@ubuntu:~$ cp /srv/ftp/201*/wh
do I redirect error messages? Note: The following information pertains primarily to Bourne-like shells, such as sh, ksh, and bash. To redirect standard error messages to a file, enter: streams and messages in unix command 2> file Replace command with the command you want to execute and how to send messages in unix file with the file to which you want to direct the errors, for example: gunzip * 2> ~/errors If you ubuntu error messages wish to suppress error messages, enter: command 2>&- If you wish to redirect error messages to standard output, enter: command 2>&1 You can direct both standard error and standard out messages to an http://unix.stackexchange.com/questions/192042/how-do-i-suppress-error-messages-from-cp output file by entering the following: command > file 2>&1 The csh and tcsh shells have substantially less flexible redirection capabilities. However, from sh or tcsh you can invoke a Bourne-like shell to run a command that redirects standard error messages. To redirect standard error messages, enter the following: ksh -c 'commands' You can use sh or bash in the place of ksh. Replace commands with redirection https://kb.iu.edu/d/agvw syntax, for example: ksh -c 'ls -l foo 2> ~/notfound' At Indiana University, for personal or departmental Linux or Unix systems support, see At IU, how do I get support for Linux or Unix?
