Does it have to be shell script or you can use Perl?

I beleive in Perl it would be

if (/\.\/(.+):.*BL(.*)/) {
$mytext = $1;
$mydate = $2;
}


in sed the syntax will be slightly different:
/\.\/(.+):.*BL(.*)/p $1 $2
but this I did not...

You could "print" the value to the standard output in script 2:
print $PID or echo $PID
In script1 get it to a variable:
tmp=`script2 p1 ...`
The tmp variable will have your value....

Vi is the most popular editor for two reasons, as I see it.
1. (And this reason is respectful) vi can be found in almost all environments.
2. (This reason should not exist if we were honest and...

It is a symbolic link, i.e. a file containing a name the link points to. That file might be deleted, but the link remains intact. Delete the link or move it to another directory and try again.

Use -d option with perl:
perl -d <myprogram>

Check what is the "usage" file. What are its permissions?

If I understand your question you need df or du command.

Try
sed -e 's/$/hour:min/' InFile >OutFile

I have not worked with ex, but it looks like you meant that it was adding in the beginning, not in the end, to add in the end use the same construction...

Try du and sort.

if [[ $loginID != "" ]]
then
/usr/ucb/sed '/^'$loginID'/d' /user/file1 > /tmp/tmp1
mv /tmp/tmp1 /usr/file1
fi
or
/usr/ucb/sed '/^'$loginID'/d' /user/file1 > /tmp/tmp1
if [[ ! -s...

"Hands-On KornShell Programming" by Rosenberg
"Learning the Korn Shell" by Rosenblatt

Why do you put the pattern in parantheses?
Try ($ev_time,$rol)=split /\./,$inputfile;
And I beleive that $inpfile is a string containing you value. True?

There is a nice command "apropos" that lists man pages if you do not know the exact name. Try for example "apropos directory".
You will get a long output, so it would be better to limit it to...

It always pays to read man pages: man ksh. This will be your reference for future, but it is not an easy way to learn scripting.
I can suggest either of these:

Sorry, I did not quite understand your problem.
You have two file systems mounted in the direcories sapdata1 and sapdataA which are in the directory /oracle/dir1, right?
Both sapdata1 and sapdataA...

It's pretty weird.
Is there anything else in the script between the lines you have typed? I mean could it be that the variable is not known when fireit is executed.

Why would not you run your...

I did not quite understand what you mean by "to hide the login name and password ....during FTP ....in the script.."
I think that it is not safe and that's why it is not easy.
May be you could use...

Try this:

perl -e 'while(<>){s/(.{35})/$1\n/g; print;}' myfile > result


Explanation (in case you are not familiar with Perl):

while(<>) starts a loop on every line of standard input...

In Korn Shell you can use the set command:

spd01: /home/obd/tst > set $(echo george bush)
spd01: /home/obd/tst > print $1
george
spd01: /home/obd/tst > print $2
bush
spd01: /home/obd/tst >
...

Sorry, in my previous post I did not mention that youhave to read without waiting for the opertion to complete.

I did not quite understand how free are you to interfere with the file.
If you cannot catch it when it is written, may be you could pipe the output of "tail -f file1" to the program in C that would...

I had similar problem once. I have created a script doing the work and then a short C program that was setting UID to root and executing the script. The compiled progam should be owned by root and...

You could use the tail command. But to get lines counted from the beginning of the file specify the line number with the '+' sign:
tail -n +123456789 myfile.
To get just one line pipe it to "head...
