looking at your req i suggest you using

It's amazing it can process files 20Gb in size, considering the average HDD size back then was less than 240MB

You have a 20-year-old version of gzip.

You may have a 32bit implementation of gzip -= the file command will show something like below - note the text in red. I would guess 32bit in your case.

file /usr/bin/gzip
/usr/bin/gzip: ELF...

From gzip documentation -
Compression is always performed, even if the compressed file
is slightly larger than the original. The worst case expan-
sion is a few bytes for the gzip...

There is of course some overhead but very little since, as you noted, it's smart enough to switch algorithms when faced with a file that compresses badly. It's much better than some older...

gzip won't ever make a file that much larger than it started, so it must be meaning the opposite of what you think.

To install "uuencode" install the package "bos.net.uucp" (should be on first CD). "lftp" is free software and probably not available in binary form for AIX. Download it, compile it, package it to a...

I don't think those work inside []

And anyway, your expression is simple enough there's little need.

First off, exec is nothing like the first two. exec does a variety of things from executing a command without returning(the shell is replaced by the new command), as well as opening/closing files.

./script creates a new shell and executes each command in the script within the new shell. When the end of the script file is encountered, the new shell exits. Any changes in the new shell caused by...

One common way is to run the script (https://www.unix.com/man-page/OpenSolaris/1/script/) command before launching the commands you want the output to be both displayed and saved.

Hi
Maybe that's what you mean ?


$ Table_1=tbl1_c1
$ Table_2=tbl2_c1
$ Query='$Table_1 Join $Table_2'
$ echo $Query
$Table_1 Join $Table_2
$ eval echo $Query
tbl1_c1 Join tbl2_c1

I'm not quite sure what the issue you're having is. It seems the solution Bartus posted should work. For funsies though, you could probably do it like this:

(19:12:02\[root@DeCoBoxOmega)...

This won't work for you? Table_1=tbl1_c1
Table_2=tbl2_c1
Query="$Table_1 Join $Table_2"
echo "$Query"

find . '(' -name '*_[0-1][0-9][0-3][0-9].c' -o -name '*_[0-1][0-9][0-3][0-9].cpp' ')'

Hi


find . | egrep '.*_[0-1][0-9][0-3][0-9].(c|cpp)$'

Hi.

Note that with the regex option in find, one needs to match the entire path. Matching arbitrary strings with a regex requires .*, not a stand-alone *:
-regex pattern
...

You probably confuse "regexps" with "shell regexps" (aka "file globs"). "Regexp" is what commands like sed, awk, grep, etc. use. The shell (and hence "find" uses only "file globs", which are a lot...

Shell is shell, awk is awk, they are independent and unrelated. Using ksh has nothing to do with whether you get gsub.

On some systems, especially Solaris, you need to use nawk to get gsub.

What are you calling the awk with? Many shells only support single diminsion arrarys, i.e. a list. If you have few enough items, then you might get away with using a formula to convert your 2D plan...

I'm not familiar with ksh,sorry

You cannot print to one file and get it to appear in two places without using an external program like tee or the like to make one line print twice. So not easily, not cleanly, and the output you...
