Full Discussion: Error output of cat to /dev/null
Top Forums Shell Programming and Scripting Error output of cat to /dev/null Post 302493936 by methyl on Friday 4th of February 2011 08:30:28 AM

I stand corrected. You get the issue I mentioned with `ls` (don't try it!).

Any space characters or non-printing characters in the filenames?
Is the directory automounted from another computer?

We can check that the filename globbing is working and check that the Shell generates the complete line.
Code:
echo cat /dirA/dirB/temp*.log


Btw. I hate open-ended lists on command lines. This construct more robust:
Code:
>/dirA/dirB/final.log
ls -1 /dirA/dirB/temp*.log 2>/dev/null | while read filename
do
         cat "${filename}" >>/dirA/dirB/final.log ; REPLY=$?
         if [ ${REPLY} -eq 0 ]
         then
               rm "${filename}"
         fi
done

logger

logger(1B)					     SunOS/BSD Compatibility Package Commands						logger(1B)

NAME

       logger - add entries to the system log

SYNOPSIS

       /usr/ucb/logger [-f filename] [-i] [-p priority] [-t tag] mm
	    [message]...

DESCRIPTION

       The  logger  utility  provides a method for adding one-line entries to the system log file from the command line. One or more message argu-
       ments can be given on the command line, in which case each is logged immediately. If message is unspecified, either the file indicated with
       -f  or  the  standard  input is added to the log. Otherwise, a filename can be specified, in which case each line in the file is logged. If
       neither is specified, logger reads and logs messages on a line-by-line basis from the standard input.

OPTIONS

       The following options are supported:

       -i	      Log the process ID of the logger process with each line.

       -f filename    Use the contents of filename as the message to log.

       -p priority    Enter the message with the specified priority. The message priority can be specified numerically,  or  as  a  facility.level
		      pair.  For example, `-p local3.info' assigns the message priority to the info level in the local3 facility. The default pri-
		      ority is user.notice.

       -t tag	      Mark each line added to the log with the specified tag.

EXAMPLES

       Example 1 Logging a message

       The command:

	 example% logger System rebooted

       will log the message `System rebooted' to the facility at priority notice to be treated by syslogd as other messages to the facility notice
       are.

       Example 2 Logging messages from a file

       The command:

	 example% logger -p local0.notice -t HOSTIDM -f /dev/idmc

       will  read from the file /dev/idmc and will log each line in that file as a message with the tag `HOSTIDM' at priority notice to be treated
       by syslogd as other messages to the facility local0 are.
