I am very very new to Linux, so please treat me like an idiot.
I am trying to install software which has a custom installer, the lines that concern me are :-

#!/bin/sh
...
CRYPT="crypt"
...
if test "${CRYPT}" != ""; then
${CRYPT} < ${PACKAGE} | ((${GZIP} -dc | tar -xvf -) >> ${LOGFILE} 2>&1)
else
(${GZIP} -dc ${PACKAGE} | tar -xvf -) >> ${LOGFILE} 2>&1
fi
chmod u-w ${RELEASE}/lib/*/*.{sl,so}* >/dev/null 2>&1
echolog "================="
...

...indicates lines I have removed for brevity, the install script is 400 lines long.

It seems to go ok until the call to 'crypt'.

On my system (redhat 8) crypt appears as 'crypt.h' which can't be called as a command, and as I don't really know what the installer wants it for, I don't know how to get around it.

If anyone has any ideas, I will greatfully receive them!

what error message do u receive? post it...
cheers, jens

Thanks for your reply, I've sorted the crypt problem now, I found that 'crypt' is an old unix command not implemented in linux which encrypts the file with a known key. There are analogues of crypt with the same functionality to download, which I did, and that solved the problem.

As we all know the command "crypt" on solaris, which does encryption,
so what is the equivalent command on linux, if not give me the procedures for doing encryption of file on linux systems (Redhat)

or tell me is there any rpm's to installed for the crypt command on linux

Advance thanks.
