syntax error: unexpected end of file when sourcing a file in bash

Question

I am getting unexpected end of file error when use using source command to source a file.

I know how to use if..else loop in bash, this is a legacy script. The same script works properly if I run it in tcsh shell. Is there any way to make the script work both in bash & tcsh ?

below is my script,

bash>
bash> source del
-bash: del: line 6: syntax error: unexpected end of file
bash>
bash> cat del
if ( `uname` == Linux ) then
    echo "One"
else
    echo "Two"
endif
bash>

I have already tried all the below solutions but none of them worked..

Any reference on this would also be of great help !

bash and tcsh provide different languages. You can't have bash run the code of a tcsh script. If you want to source a file in bash, that file must be written in the language tha bash understands. — nos, Jul 19 '18 at 11:18
@PTRK yes i know the if..else in bash but this is a legacy script and this is not working only in bash..is there any way to make it work in both bash & tcsh ? — ArigatoManga, Jul 19 '18 at 11:22
This script do not work at `bash` shell, the `if` estructure end with `fi`, see this [link](http://www.dreamsyssoft.com/unix-shell-scripting/ifelse-tutorial.php) — Tuxpilgrim, Jul 19 '18 at 11:24
If you need use this in `bash` and `tcsh`, you can add a condition for shell type, something like: `if < echo $SHELL == /bin/bash >` — Tuxpilgrim, Jul 19 '18 at 11:28
as @nos said, bash will only understand bash code. Since tcsh and bash are different, I wont think you can achieve your goal. — PTRK, Jul 19 '18 at 11:35
In general, you probably cannot write a full script that behaves the same in `bash` and `tcsh`. For this snippet, you *could* write ``test `uname` = Linux && echo One || echo Two``. Here, `&&` and `||` are the only two pieces of shell syntax used (`test` is an ordinary external command), and they are supported by both shells. (However, `... && ... || ...` will not always work as a replacement for an `if` statement.) — chepner, Jul 19 '18 at 11:44

Please go through this link

In bash script the correct syntax for if....else is

if [ condition ]
then
        //block 1
else
       //block 2
fi

You can change your code to

if [ $(uname) == Linux ]
then
    echo "ONE"
else
    echo "TWO"
fi

Duplicate of @Pritam answer. Also doesn't answer to the original author problem. – PTRK Jul 19 '18 at 11:34

It seems it's a (t)csh source. Please try tcsh del (or csh del). Of course you should have installed csh (or tcsh).

Correct you script like below. Your if condition is not correctly closed.

system=$(uname)
if [[ $system == "Linux" ]]; then
   echo "One"
else
   echo "Two"
fi

Your `if` is not correct and would produce an error message. Substitute it by `if [[ \`uname\` == Linux ]]`. Also, since we know that the context is bash, it's besser to not use the obsolete backquotes, but write `if [[ $(uname) == Linux ]]`. – user1934428 Jul 19 '18 at 11:26
@user1934428, thanks for your advice. I have already corrected my answer – Abhijit Pritam Dutta Jul 19 '18 at 11:29
