Hi, a pipe appears to be missing:

man crontab yields :

The ``sixth'' field (the rest of the line) specifies the command to be run. The entire command portion of the line, up to a newline or %

There you are - EOF with three trailing spaces! Try without.

Hold on, hold on! How do you explain the difference in above outputs:
oracle:fs$ ps -ef|grep '[p]'mon_$ORACLE_SID
oracle 1631 1 0 Jan22 ? 00:00:54 ora_pmon_fs91dmo

From the output you have shown us, it appears that ed is doing what you requested. So, if the contents of /etc/oratab have gone back to their original state when the script terminates, it would seem...

That's right.

If select is breaking on that column, I suspect it has a newline in it.

Try changing the value of IFS to newline, so select (and shell syntax in general) only splits output on lines:

OLDIFS="$IFS"
IFS="
" You'll want to do IFS="$OLDIFS" whenever not in that loop to...

Calling the write() system call does not create a file. Only open() does that, and the only time your program does that is when you do > filename.

In UNIX, where a file is and what its contents...

I suspect it's named -p\n or some other such garbage or else you'd have been able to remove it with rmdir /-p.

If it's an empty folder, ls -li won't show anything. -d tells it to show the folder...

Hi.

It is not easy to understand code that has been extracted from a larger source. Here is a shell script that drives a portion of the bash-select-code, but rendered in perl so that you can run...

Hi, edstevens.

I like to know answers, too. However, some questions are more important to me than others -- we all set priorities.

So some of the ways to get answers for:

in order to avoid parameter expansion within the 'here-doc' (\$parameter) quote the "EOF".
Doing 'man bash" yields the following:

I don't know sqlplus and therefore I don't know what effect you hope to achieve. I also don't understand your need to use use backquotes. But try doubling the backslash.

You could try changing the field separator to something other than whitespace (e.g. a comma) - either in sqlplus (set colsep ,) or in the shell (IFS=,, and unset it afterwards).

What's the output from running Don's suggestion with sh -x?

You're making this way to hard. If your script above works, the following should work just as well without using the temp file:

awk -F\" '{print "srvctl config database -d...

I'd use a variable for that. When you detect files, change the variable, and it'll stay changed.

find may be more efficient than ls | grep.

Assuming that your file has records terminated with carriage-return line-feed, we can probably eliminate the format of the file.

To get rid of the blank, replace a comma with a blank in the awk-command. NR is a special variable which holds the current line number, as you may have guessed.

Used cut instead of awk. Not sure why "awk" doesn't list the first one.
Maybe someone with superiour UNIX knowledge can help here.
