Hi Jean,

I tried the above code in UAT server...

OS Version:

Code:

ksh:0$ uname -a
SunOS 5.9 Generic_122300-48 sun4u sparc SUNW,Sun-Fire-V440

My code is:

Code:

#! /bin/ksh
 
if /usr/xpg4/bin/grep -qE '[[:cntrl:]]' control_char_file.dat
then
    echo 'Cannot process: File contains control characters!'
    exit 1
else
    echo 'No control characters found!!!'
fi

The input file is:

Code:

F|852871
F|852872^M
- Saps.

I'm getting error like:

Code:

ksh:0$ ksh test_control_char.ksh
test_control_char.ksh[11]: usr/xpg4/bin/grep:  not found
No control characters found!!!

Permission of both files: -rwxr--r--

Please help.

Working fine now... Smilie

Hi @Alister,

1. Can we use

Quote:

[:cntrl:] character class

in perl script?

2. We have a dos2unix validation in our perl script which will get the following command from DB using SELECT query:

Code:

dos2unix -437 -q <some_file_nm>

-437 is for Key Board format message.
What will '-q' do?
