I will override the mailx function so that when mailx is called, it calls my version of maix and in that function I want to read the file which is attached in progional mailx function- abc.txt
Once done, I can do whatever I want with this data...sending it to somebody else rather to intended receipient....
Is there any way to it?
Thanks

Hi Everyone,
The machine I'm working on is an AIX 5.3 LPAR running on a P650. oslevel -r shows 5300-08. I'm trying to take a backup to a SCSI tape drive, which has been working up until this point. I know of nothing that has changed recently to cause this problem. But when I try to take a... (0 Replies)

I need to do the same for other sources.
To create new scripts and to deal with multiple bash files sounds not logical. It is a bit hard to manage for me..
I wondered if it was possible to make my input file as variable.

Hi All,
I'm creating a program which reads millions of bytes from the PIPE and do some processing. As the data is more, the idea is to read the pipe parallely.

readproctitle
readproctitle(8) System Manager's Manual readproctitle(8)NAME
readproctitle - maintains an automatically rotated log in memory for inspection by ps(1).
readproctitle is available in daemontools 0.75 and above.
SYNOPSIS
readproctitle L D
DESCRIPTION
L consists of any number of arguments. D is one argument consisting of at least five dots.
readproctitle reads data into the end of D, shifting D to the left to make room. This means that the most recent data is visible to
process-listing tools such as ps(1). readproctitle always leaves three dots at the left of D.
For example, if
readproctitle io errors: ....................
reads the data
fatal error xyz
warning abc
then its command-line arguments change to
readproctitle io errors: ... xyz!warning abc!
with a newline character in place of each !. Process-listing tools typically show the newline character as ? or
.
readproctitle exits when it reaches the end of input.
Beware that most implementations of ps(1) have small argument-length limits. These limits apply to the total length of readproctitle L D.
I have not seen a system with a limit below 512 bytes.
