How to split big file on HP-UX and join on Windows?
By prvnrk
Hi HP-admins,
I have 120GB file on HP-UX and need to split to 4GB pieces and join them on Windows.
As I don’t want to use zipsplit, tried to use split command and join on windows using “copy /b” but it doesn’t work (It merges and creates new file but file is corrupt)
What is the correct way to join UNIX split files on Windows? ( “copy /b” not working correctly)
Or is there solution for it?
Thanks

How to use MAIL command in UNIX?
By harika03
Hello All,
I have an issue where I have to send multiple filenames(only names of the file) through an email and I have to send in a single mail.
For example…Kscik.lk.txt_$currentdate,kscik_ii.txt_$currentdate. I can send it as below
echo “files n Kscik.lk.txt_$currentdate n kscik_ii.txt_$currentdate are available in so n so folder” | mailx -m -s x@g.com.
The above syntax can only send the subject that has two files but I have to send an single email where subject contains all starting with kscik* related files.
Please help on this..

Simply question about capturing output to /dev/tty
By Paul R
Suppose another person wrote the following one-line shell script:
echo $RANDOM > /dev/tty
QUESTION #1: How can the random number, which is output to the terminal by this script, be captured in a variable?
QUESTION #2: How can this be done in a cron job?
Specific code, whether in ksh or C, would be greatly appreciated.

REAL LIFE STORY: We use software with concurrent licenses, which are managed on a UNIX server. The vendor supplies a program which simply displays the number of licenses currently being used, but it directs the output to /dev/tty (not stdout/stderr/file), and it is a compiled program so it cannot be directly altered using sudo permissions. I can only assume that the vendor is actively trying to prevent their customers from gathering statistics about their concurrent license usage, because the customer might find out they don’t need so many licenses, contract for fewer licenses, and thus the vendor would loose money. 😡 The vendor has to provide some mechanism for determining license usage, but it’s extremely limited. 🙁 I would like to gather statistics every 15 minutes, find the maximum concurrent license usage, so we can contract to the vendor for the ideal number of licenses. 😀 Any help you can provide would be greatly appreciated. Thanks! –Paul.
Reversing text order of each line of a file in UNIX
My input is:
Code:
hello how are you
my chemistry book is lost
what is up
etc...
And I want the output to be:
Code:
you are how hello
lost is book chemistry my
up is what
....
I found an earlier response to a similar question but it was not accurate as it required a certain string length for each line
Record standard output and inputs made on a session
By RoshniMehta
When using Oracle, we have an option to turn spool on, which records that transactions and output to a file. Any such options on UNIX, where I can get everything I have on my screen into a file? That would be helpful in documenting the OS level changes that I perform manually.

Question about UNIX file rights
By mike_bn
Hello experts,
i am a Unix beginner and to test the rules of file rights (rwx)
i created the file
/root/testdir/subdir/test.sh
and set the rights of testdir,subdir, test.sh (using chmod) to various configurations in order to get an idea
in which case you need which rights. Test commands were
– ls (‘Can i read the directory in certain change-mod configurations?’)
– less test.sh (‘What are the requirements in terms of rights to be able to read a file?’)
– test.sh (‘When can i execute a file?’)
My question is, when testing unix access rights, is there a difference
between referencing test.sh by
./tests. and /root/testdir/subdir/test.sh?
I know that for the first command, i need to be in the directory, but in terms of
access rights, are these to ways of referencing the file test.sh totally equivalent? In other words, does
‘less ./test.sh’ always work when ‘less /root/testdir/subdir/test.sh’ and vice versa?
Or is there a configuration for the rights of testdir and/or subdir where one works, and the other not? Same question with executing.
Thands in advance for your help!
Mike
