Answer 1

export is a Bash builtin, echo is an executable in your $PATH. So export is interpreted by Bash as is, without spawning a new process.

You need to get Bash to interpret your command, which you can pass as a string with the -c option:

bash -c "export foo=bar; echo \$foo"

ALSO:

Each invocation of bash -c starts with a fresh environment. So something like:

bash -c "export foo=bar"
bash -c "echo \$foo"

will not work. The second invocation does not remember foo.

Instead, you need to chain commands separated by ; in a single invocation of bash -c:

bash -c "export foo=bar; echo \$foo"

Answer 2

Probably because it's trying to execute "export" as an external command, and it's a shell internal.

Answer 3

If you are using C shell -

setenv PATH $PATH":/home/tmp"

Answer 4

SHELL is an environment variable, and so it's not the most reliable for what you're trying to figure out. If your tool is using a shell which doesn't set it, it will retain its old value.

Use ps to figure out what's really going on.

Answer 5

change from bash to sh scripting, make my script work.

!/bin/sh
