in my bash script I've many lines executing commands with redirection to log files.
The trailing part of these lines doesn't look nice and I like to put it into a variable.
The (not working) idea is something like that
thanks for suggestions

We have a script that runs in ksh on HP-UX 11.11. It takes three arguments. The last argument can be a filename or wildcard character. For example:
script -s hello -t goodbye '*.d*'
In a case such as this, I would wrap single quotes around the final argument because I dont want the shell to... (4 Replies)

MYPID=$$
MYNAME=`basename $0`
LOGGER="/usr/bin/logger -t $MYNAME($LINENO) -p daemon.error"

echo 'this is an entry into the log file' | $LOGGER

I'm in the habit of using the following type of loop structure:
for num in `seq $1 $2`

doneWhile `seq $1 $2` is not exactly a huge resource hog, I would like to learn a better way. It seems that brace expansion is a good way to go:
for num in {3..10}The problem, though, is... (2 Replies)

The objective of the code below is to create sed script to be later executed. However, it bonks because $ARCHIVENAME expands to a directory specification so the forward slashes cause problems. I can think of a few solutions that would involve redesigning the process, but I'm hoping there might be... (4 Replies)
So, I was bored on the train today, and was thinking of ways to loop through elements of an array. I came up with the following simple script, but it doesn't work as brace expansion doesn't seem to work with variables. Is there something I'm missing, or does the shell just not work like this?

dirname
BASENAME(1) BSD General Commands Manual BASENAME(1)NAME
basename, dirname -- return filename or directory portion of pathname
SYNOPSIS
basename string [suffix]
basename [-a] [-s suffix] string [...]
dirname string [...]
DESCRIPTION
The basename utility deletes any prefix ending with the last slash '/' character present in string (after first stripping trailing slashes),
and a suffix, if given. The suffix is not stripped if it is identical to the remaining characters in string. The resulting filename is
written to the standard output. A non-existent suffix is ignored. If -a is specified, then every argument is treated as a string as if
basename were invoked with just one argument. If -s is specified, then the suffix is taken as its argument, and all other arguments are
treated as a string.
The dirname utility deletes the filename portion, beginning with the last slash '/' character to the end of string (after first stripping
trailing slashes), and writes the result to the standard output.
EXIT STATUS
The basename and dirname utilities exit 0 on success, and >0 if an error occurs.
EXAMPLES
The following line sets the shell variable FOO to /usr/bin.
FOO=`dirname /usr/bin/trail`
SEE ALSO csh(1), sh(1), basename(3), dirname(3)STANDARDS
The basename and dirname utilities are expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
