Shell Programming and Scripting

when using I/O redirection to program another program from a script, how can you keep the program open in an interactive state without closing. For example:

gdb <<EOF
file a.out
run
EOF

this will open up gdb and run the commands and then close... how can I make it so I can open up a program (not limited to gdb) and keep it open after running a few starting commands?

I tried putting something other than EOF, but no matter what it seems to quit the program after the script has run.

Try sourcing your script instead of just executing it i.e.

Code:

. path_to_your_script

nope, that won't work either, but, I do have a question about your reply, what does "sourcing it instead of executing it" do?

as far as progress towards the original question, I tried simply removing the terminator, with no luck...

Code:

gnuplot <<ENDCAT
plot sin(x)

Reading the man page would have give you this for gdb.

There is no simple generic way to do this.

Code:

cat > file <<EOF
file a.out
run
EOF

gdb -x file

for gnuplot:

Code:

cat > file2 <<EOF
plot sin(x)
EOF

gnuplot file2 -
