Unable to source a simple bash script

问题

I understand similar questions to this been asked in SO multiple times. However, I couldn't find any usual suspects here.

#!/bin/bash
myvar="test"
if [ "$myvar" == "test" ]
then
echo "Test mode"
fi

Spent quite some time on it. Can anyone advice what am I missing?

I am able to execute the script, but couldn't source the same.

error while source bash: test.sh: line 7: syntax error: unexpected end of file

$ which bash
/bin/bash
$ bash --version
3.2.57(1)

I am able to get the same working on my another Mac. So, it's pretty much something wrong on my Mac, but couldn't figure out what it is. Also, not only the above-mentioned script, any script with "if" condition I couldn't source. Tried different examples mentioned here, same syntax error.

$ file test.sh 
test.sh: Bourne-Again shell script text executable, ASCII text

$ hexdump -C test.sh

回答1:

Check for newline character differences or encoding pages. if it something as simple as this and there is a mac involved, always check that first

回答2:

As other users already stated, you can check if newline is LF because CRLF will fail in linux. if you convert the script it should be fixed. you can install a tool which can convert CRLF into LF:

dos2unix test.sh

Regarding the sourcing, not sure if this may help you with your issue. assuming the wrapper script which sources test.sh is not called from bash...

#!/bin/sh
. ./test.sh

...the if statement will fail, because bourne shell does not support '==' but if you change it to...

#!/bin/bash
myvar="test"
if [ "$myvar" = "test" ]

...the script will sourced without errors. Please note it depends on how the script is sourced, the shebang might be ignored

Okay finally, found the issue.

I removed my .bashrc file and its working fine. Looks like something in .bashrc was messing it.

$ source test.sh
Test mode

Thanks, everyone appreciate it.
