Read command
Hi everyone,

I have problem while writing a shell script for linux (Red Hat).

First I need to create a read command. I tried to google this but so far I can't sort this out. I hope you will be able to help me.

I have to read a file like this :

GESTION_DATA_SET_variable1_variable2

Variable1 could only be : ELS or IMA or NPI or NPD

variable2 could only be : 0 or 1 or 2

so I am writing step by step a script do to different things but fisrt the script should read the file wanted.

Code:
#!/bin/bash

# INSTRUMENT

instrument_name=$4
if [ "$instrument_name" == "" ]
then
   echo "Instrument Name (usage ELS ; IMA ; NPI ; NPD) : \c"
   read instrument_name
fi

# PHASE

phase_name=$5
if [ "$phase_name" == "" ]
then
   echo "phase name is numeric value (usage 0 ; 1 ; 2) : \c"
   read phase_name
fi


#------------------------------------------------------
# fonction

jboss () {
        rdate=$(cat GESTION_DATA_SET_${4}_${5} | awk '{printf "%s\n" ,$2"_"$3}')
        echo ${rdate}

}

#------------------------------------------------------

jboss

sleep 2

exit

so far the script is unable to complete the file name correctly as the output screen shows error that No such file or directory : GESTION_DATA_SET__

I hope you will be able to help a such dummies : )

rdate

rdate(1M)                                                 System Administration Commands                                                 rdate(1M)

NAME

       rdate - set system date from a remote host

SYNOPSIS

       rdate hostname

DESCRIPTION

       rdate sets the local date and time from the hostname given as an argument. You must have the authorization solaris.system.date on the local
       system. Typically, rdate is used in a startup script.

       The inetd daemon responds to rdate requests. To enable inetd response, the lines invoking the time command in inetd.conf must not  be  com-
       mented out.

USAGE

       The rdate command is IPv6-enabled. See ip6(7P).

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:
