Sounds like something called a "here doc" might be what you are looking for. If you are looking to have a bunch of lines written from the script into a file, you can use this in either Kshell or bash:
Code:
cat <<endKat >/tmp/test-file
this is line one
this is line two
this is line three
endKat
All lines that follow the cat command, until endKat is reached, are written to the named file (/tmp/test-file in this case). I use endKat as the ending marker string as it isn't likely to be in any text that comes before it.
Have a look at the Kshell documentation for more info on here documents.
Thanks bunch for your reply , ya similar to this only i wanted...
So, if we give any string which is not present in the file, it will write everything in named file after cat command until EOF is reached? can you also help me more with exactly what "<<" implies?
Thanks once again for your help !
ps: Also, am able to execute this "test-file" being made here without assigning execute permission on this.
set -A arr a1 a2 a3 a4
# START
ssh -xq $Server1 -l $Username /usr/bin/ksh <<-EOS
integer j=0
for loop in ${arr}
do
printf "array - ${arr}\n"
(( j = j + 1 ))
j=`expr j+1`
done
EOS
# END

this is not giving me correct output.

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
