Variable has spaces around the string, need to remove them
Hi all, I'm a newbie to the Linux world and I got a couple of shell script questions:

(1) How do combine two variables and make it equal to a third variable? For example, I got a variable $A=FirstName, $B=LastName, and I want to combine the variable into one variable so when you echo the final variable, it looks like "Joe Smith", not "JoeSmith". What is the exact syntax for that? (Im using bash shell script)

(2) Down below is a script that I executed called testfile. When I execute, note the bold face item where there is a space between the numbers 516 and 10757. How can I get rid of the space before and after those two numbers? The string I need to output is a little bit tricky...Im puzzled on this one.

Thanks in advance for your response.

[root@mymachine mikey]# sh testfile
Oct
516
10757
Mycmd1 is next
get "$$ BID=# 516 " RPT132.20051012
get "$$ BID=# 10757 " RPT590.20051012





my script looks like this:

[root@mymachine mikey]# cat testfile
# Set date
curdate=`date +%Y%m%d`
mondate="Oct 12"
#daydate=`date +%d`
#totaldate=$mondate . $daydate
mondate=Oct
daydate=12
#totaldate=$mondate + $daydate
cat filelist.txt | grep -i "Oct 12" | grep -i rpt132 > mike1.txt
cat filelist.txt | grep -i "Oct 12" | grep -i rpt590 > mike2.txt

echo $mondate
#
# Strip the Batch ID from the listing of the file
#rm mike1.txt
#rm mike2.txt
batchid1=`cat mike1.txt | cut -nb 27-36`
echo $batchid1
batchid2=`cat mike2.txt | cut -nb 27-36`
echo $batchid2
echo "Mycmd1 is next"
mycmd1="get \"\$\$ BID=#$batchid1\" RPT132.$curdate"
echo $mycmd1
mycmd2="get \"\$\$ BID=#$batchid2\" RPT590.$curdate"
echo $mycmd2

asadmin-multimode

asadmin-multimode(1AS)													    asadmin-multimode(1AS)

NAME

       asadmin-multimode,  multimode  - allows you to execute multiple commands while preserving environment settings and remaining in the asadmin
       utility

SYNOPSIS

       multimode [--file filename] [--printprompt=true] [--encoding encode] [--terse=false] [--echo=false]

       Use multimode to process the asadmin commands. The command-line interface will prompt you for a command, execute that command, display  the
       results	of the command, and then prompt you for the next command. Additionally, all the asadmin option names set in this mode are used for
       all the subsequent commands. You can set your environment and run commands until you exit multimode by typing "exit"  or  "quit."  You  can
       also provide commands by passing a previously prepared list of commands from a file or standard input (pipe). You can invoke multimode from
       within a multimode session; once you exit the second multimode environment, you return to your original multimode environment.

       This command is supported in local mode only.

       --file		       reads the commands as defined in the file.

       --printprompt	       allows the printing of asadmin prompt after each command is executed. Set this option to false  when  the  commands
			       are piped or redirected from the standard input or file. By default the option is set to true.

       --encoding	       specifies the locale for the file to be decoded.

       --terse		       indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well-
			       formatted data for consumption by a script. Default is false.

       --echo		       setting to true will echo the command line statement on to the standard output. Default is false.

       Example 1: Using multimode to execute multiple commands

       example% asadmin multimode --file commands_file.txt

       Where: example% is the system prompt. The multimode settings are executed from the commands_file.txt file.

EXIT STATUS

       0		       command executed successfully

       1		       error in executing the command
