If the printer is directly network attached (Xerox, Ricoh, HP, .......) you may need the software or script from the supplier to drive them. If the printer is attached to another server, then your...

If exec can't find the interpreter, none of the script executes, including set -x.

It's almost certainly a carriage return at the end of the interpreter line. Not only would it explain why the...

That's massively inefficient. There's no need to invoke grep once per line.

If the lines in fileA.log are not regular expressions, use fixed string matching.

The first cat command it's...

Try adding set -x to the top of your script below the #!/bin/sh line, run it again, and provide the output.


#!/bin/sh
set -x

Looks like a carriage return at the end of the shebang (probably a result of editing in Windows).

Show what you're running that produces that error.

If you're using GNU Sed


sed --version | grep GNU


this should take care of all three in the file:


sed -r '/^$|-|PRCSINSTANCE/d' file

That seems straightforward enough, however, you list three different files (see below). Please explain further.


Sfile=/u01/scripts/Sfile.log
Pfile=/u01/scripts/Pfile.log...

Sfile=/path/filename
sed -i.BKUP '/^$/d' $Sfile
-i option is in place replacement, sed will take backup of your original file as "filename.BKUP"

echo $Sfile | sed -i.BKUP '/^$/d'

Should like cjahdskjah aaaaSTUFF xyz be deleted from fileB.log in your example?

If not modify Yoda's solution as follows:

grep -vwf fileA.log fileB.log

Hi,
You must use $line versus $FileA in your line sed:
sed -i "/\b$line\b/d" $File_B

But, your solution read/write file2 as far as number line from file1

Better solution:
$ printf...

grep -vf fileA.log fileB.log

Also, that case expression does an exact match. If you want a substring match:

*ABCD*|*ASDF*|*WEDF*|*YUIO*)

You havent respected the strict syntax of case...


case "$var1" in
ABCD|ASDF|WEDF|YUIO) echo The queue is $var1
;;
*) echo "No match"
;;...

Please use [CODE] tags, not [ICODE] tags.

Anyway, can you have a newline after the in keyword and the expression and see if that helps. Look at the example given for the neat way to write code...

That is not how case works, reread the example shown to you.

case "$var1" in
val1|val2|val3) echo $var1 found ;;
esac Variable is in red, expression is in green.

The newlines, ), and ;;...

$ var1="a"
$ if echo 'val1 val2 val3' | grep -wq "$var1" ; then
> echo Match found
> fi
$

I would go with Subbeh's second option, the case statement.

There are two reasons for this, because the echo....grep ...:-

creates extra processes, so in a loop, this could be costly to the...

Either use grep:
if echo 'val1 val2 val3' | grep -q "$var1" ; then
echo $var1 found
fi
or case:
case "$var1" in
val1|val2|val3) echo $var1 found ;;
esac
