Try:
tr -d '\0' < file_with_nulls > file_without_nulls
Note that the filename you use for the output file must NOT be a name of your input file.

Hold it. We all are just poking in the dark.

Hi, OK.

So to match 6 digits on a line only, try:
/^[0-9]\{6\}$/{

Also note that a \ inside square brackets denotes a literal \ character, not an escape.

Your data sample show a first line with 6 digits, whereas your sed script in post#1 tests for 6 digits followed by any character that is neither . or a \ . So the script will not match the first line...

Assuming that your sort utility has a -M option (which is not required in standard sort utilities), you might want to try the following:
sort -k9,9n -k5,5M -k6,6n -k7,7

Confusing specification, many wild guesses!

How about
awk '
{TYPE = substr ($4, 1, 1)
sub (TYPE, "", $4)
print $1, $2, "PIC " (TYPE~/[SN]/?TYPE:"") "9(" $3-$4 ")"...

Doesn't this work?

grep -v "T$" filename |egrep -v "^$" |sort | cut -c 1-78,80

Could the two greps also be condensed into
egrep -v 'T$|^$' filename ...

To keep from getting false positives (Chubler_XL and RudiC, try your suggestion with $1 set to OE and $2 set to Jo with your test dataset) by actually matching the double quotes in the file, one...

What do you need the single quotes for? Did you try without?

Try using:
ls -lrS
also:
if [ "$1" = "-r" ]

( -eq is for numerical comparisons )

Pass the search pattern as the 1st argument to your script, then:
# If not .savenn file, show name and result of grep.

pattern=$1
shift
for i in "$@"
do
echo $i |grep -q 'save[01][0-9]'

Hi,

The inode thing is exactly what I've always done in this situtation. But I just thought I'd have a play about and see if I could find another answer, and there's this approach too (which...

Hi.

If for just this file in this directory:
mv -i "Wrong*Right" Right
Otherwise use the scripts noted in previous posts.

Best wishes ... cheers, drl

Try ls -i to get the inode of the file. This will uniquely identify it without depending on the filename. Then you can give that inode to find and have it feed the filename into mv for you.

$ ls...

You should use either curl or wget .

There are ways to directly enter escape characters into shell commands, but the method varies depending on what shell you're using, command history editing mode, etc.; but the following should work...

Would mv -i *G or rm -i *G help? Apply utmost care when answering the confirmation question!

cd to the folder it's in, get its inode number with ls -li, then

find . -inum inodenumber -exec echo rm '{}' ';'

Remove the 'echo' once you've tested it and are sure it does what you want.

Hi.

I don't use COBOL, but a quick glance at the results of a search for COBOL statement syntax yielded a possibility for a solution: COBOL: Language Reference...

I guess - as it is not too clear - that you want the second grepto match your file. Try the alternation (using | ) in a subexpression:grep -E 'AAA-BBB([^-]|$)' file (you may have to switch on...

Using a $ anchor you can address all trailing characters
grep 'AAA[^-]*$' file

I implied you needed to use ksh for that. It should be your default shell, IMO, giving what SCO's documentation lists as available (ksh, csh, sh).

I don't have access to SCO but no sh should have...

I'm not sure I understand what you're trying to do, but if I'm guessing correctly, try:
