}
But I get this error
Code:
sed: -e expression #1, char 0: no previous regular expression
And all the files are replaced by empty files. I would like to substitute only the files where the pattern search actually did something, and if it's possible, keeping the original file permissions.
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:

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

I'm in the habit of using the following type of loop structure:
for num in `seq $1 $2`
do
command
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)
Hi forum,
in my bash script I've many lines executing commands with redirection to log files.

xyz_cmd 2>&1 > $BASENAME.$LINENO

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?
