Ok... so in general we have an old SysV vs. Berkley... or perhaps a ksh vs. Berkley-ism.
I too was somewhat displeased with the Linux choice of a BSD-ish like echo since it tried to be more POSIX which made is smell more SysV like (Linux is sort of its own blend).
So the niceness of echo "first line\nsecond line" that you had in HPUX, Solaris, etc.. well, you had to do echo -e "first line\nsecond line" in Linux. Now... with more contemporary versions of ksh, they've added a "do nothing" option of -e, which means for any system running ksh93 (maybe even something less) but not not a really old ksh, you could use -e to make scripts seemingly portable.
But... maybe you plan to run ksh93 on your Linux host.
Then, you can run the following:
Code:
$ builtin getconf
$ getconf UNIVERSE = att
$ echo "hello\n\nthere"
hello
there
$
Sadly, even getconf syntax has changed over the years, for the command getconf UNIVERSE = att, you may have to use a minus instead of an equals....
Now... with regards to that latter solution, if you whole system runs in ksh and uses a non-systemd SysV style init, you could put that stuff there, but of course I can pretty much guarantee you that your distro producers didn't have portability in mind when they wrote their init scripts. So... it will likely render your system useless to try change away from bash.
There's like a KSHENV var that might be able to pull such things in for any ksh script..... it's been too long.. anyhow, might get you pointed in the right direction.
On Linux I could use the `watch` command to loop a command X times. Is there a similar command on AIX? If not, is there a way to write a loop on the command line to do this?
Linux: watch -d -n 60 'db2 list applications show detail | grep Connect | wc -l'

To list file permission/access right in octal format, linux has a command 'stat'. For example, we can use the followin -

Please advice. (3 Replies)
I'm having a problem regarding the encoding of my files in Linux and AIX.
I have a file which can be viewed both in Linux and AIX (via NetApp mount). When I checked the encoding, they have difference.
In Linux, the file is encoded as ISO-8859 text. (checked by using "file" command).... (1 Reply)
Hi All,
The scripts developed in AIX can be executed in Red Hat Linux too? Because, we are migrating OS from AIX to LINUX.
Will there be any differences in commands?
Thanks in advance!!!
