syntax error running shell program in bash (Centos 5.9)

I'm trying to run this simple shell program. I'm new to the shell programming but it was downloaded from the Paypal site for helping set up encrypting buttons.

Here's there error:

bash line 44: syntax error: unexpected end of file

What's wrong with the code? Sorry, I commented out the setenv command lines because it didn't run in bash. I read this:

To set an env variable you will need to to it like this


for CLASSPATH example
Make sure that you have the AXIS_HOME variable set correctly.

this is designed to be csh not bash, but it should invoke csh when run from bash

please try running as "source"

Since line 1  reads "#/bin/csh" instead of "#!/bin/csh" the script will be executed by your login shell, or, as you invoked it, by bash, and not by csh.

If this is what you desire please note that bash does not understand "endif" - it should be "fi"

Hi @Thomas, Is that setting the env for bash or csh or both?

woolmilkporc is correct. However NickUpson is also correct in a sense that this particular script makes no sense if invoked in an embedded shell. It echoes something in if-else, but the export CLASSPATH part will have no effect since it loses its scope when the script exits. I.e. you *must* source this instead of executing, as visible in second line's hint.

The conditional structure in csh is:

if condition then
else if cond then

Open in new window

same in bash:
if condition; then
elif cond; then

Open in new window

I.e. keywords are different and semicolon is a *must* in bash.
Note also that the test is [ ... ] in bash (the opening bracket is actually a shell builtin), i.e.:

But I recommend using "test" instead which is either a shell builtin or a binary executable (or both), thus independent from the shell and has the same syntax:

if  test -d $CRYPTO_HOME; then
	echo setting crypto home to $CRYPTO_HOME
        echo cannot find crypto distribution ...
        exit 1

Open in new window

The only blocking point is the existence of semicolon; it is needed in bash but not needed in csh. I don't know if it works in csh with semicolon as well. You may work around using && and ||

test -d $CRYPTO_HOME && echo setting crypto home to $CRYPTO_HOME
test -d $CRYPTO_HOME || (
    echo cannot find crypto distribution ...
    exit 1

Alternatively you may make it a mule:

# Please source this file.
export CRYPTO_HOME=/home/myultrat/ssl/paypal/crypto-150

/bin/csh -c "if (-d $CRYPTO_HOME) then
	echo setting crypto home to $CRYPTO_HOME
        echo cannot find crypto distribution ...
        exit 1
export CLASSPATH=.

Open in new window

Note that exports are *outside* of shell invocation but the conditional structure is *inside*.
