sh script if then else error

[Glenn De Vriendt]

@luz

Thanks for your reply. I tried both: the then on the second line and with a ; but it is the same:
if [ "$1" = "1" ]
then
echo €€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€
echo €€ launching webradio Hitradio Maroc... €€
echo €€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€
url=http://hitradio-maroc.ice.infomaniak.ch/hitradio-maroc-128.mp3

elif [ "$1" = "2" ]
then
  echo €€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€
  echo €€ launching webradio Topradio... €€
  echo €€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€
  url=http://jwmp3.topradio.be/topradio.mp3
#else
  echo €€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€
  echo €€ launching webradio Hitradio Maroc... €€
  echo €€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€
  url=http://hitradio-maroc.ice.infomaniak.ch/hitradio-maroc-128.mp3
fi

result: line 36: syntax error: unexpected end of file (expecting "then")

and
if [ "$1" = "1" ]; then
echo €€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€
echo €€ launching webradio Hitradio Maroc... €€
echo €€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€
url=http://hitradio-maroc.ice.infomaniak.ch/hitradio-maroc-128.mp3

elif [ "$1" = "2" ]
then
  echo €€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€
  echo €€ launching webradio Topradio... €€
  echo €€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€
  url=http://jwmp3.topradio.be/topradio.mp3
#else
  echo €€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€
  echo €€ launching webradio Hitradio Maroc... €€
  echo €€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€
  url=http://hitradio-maroc.ice.infomaniak.ch/hitradio-maroc-128.mp3
fi

but result also in line 35: syntax error: unexpected end of file (expecting "then")

I really don't know what I do wrong.

Best regards,
Glenn

@Glenn-De-Vriendt I'm afraid using € character(s) in shell script is a bad idea.

This can be a working version of your script (19 lines).

#!/bin/sh
if [ "$1" = "1" ]
then
  echo "####################################"
  echo "## launching webradio Topradio... ##"
  echo "####################################"
  url=http://jwmp3.topradio.be/topradio.mp3
elif [ "$1" = "2" ]
then
  echo "####################################"
  echo "## launching webradio Topradio... ##"
  echo "####################################"
  url=http://jwmp3.topradio.be/topradio.mp3
#else
  echo "##########################################"
  echo "## launching webradio Hitradio Maroc... ##"
  echo "##########################################"
  url=http://hitradio-maroc.ice.infomaniak.ch/hitradio-maroc-128.mp3
fi

The same script without some unnecessary lines (14 lines).

#!/bin/sh
if [ "$1" = "1" ]
then
  echo "####################################"
  echo "## launching webradio Topradio... ##"
  echo "####################################"
  url=http://jwmp3.topradio.be/topradio.mp3
elif [ "$1" = "2" ]
then
  echo "##########################################"
  echo "## launching webradio Hitradio Maroc... ##"
  echo "##########################################"
  url=http://hitradio-maroc.ice.infomaniak.ch/hitradio-maroc-128.mp3
fi

Happy scripting!

[Glenn De Vriendt]

@György-Farkas

Thanks for your tips. I changed the € into # and the quotes after echo. The else was for having a default (which I would change later in the first if => $1 = 1 OR $1 IS NULL).

if  [ "$1" = "1" ]
then 
  echo "##########################################"
  echo "## launching webradio Hitradio Maroc... ##"
  echo "##########################################"
  url=http://hitradio-maroc.ice.infomaniak.ch/hitradio-maroc-128.mp3
  
elif [ "$1" = "2" ]
then
  echo "####################################"
  echo "## launching webradio Topradio... ##"
  echo "####################################"
  url=http://jwmp3.topradio.be/topradio.mp3
fi

I still have the same error:
####################################
'## stop playing sounds... ##
####################################
: no process killed
parameter
: not found: line 8:
webradio.sh: line 36: syntax error: unexpected end of file (expecting "then")
root@Omega-FAF7:~#

Even if I run the most basic script I get the same error:

#!/bin/bash
# Basic if statement
if [ 1 = 1 ] 
then
  echo "Equal"
fi

if.sh: line 6: syntax error: unexpected "fi" (expecting "then")

I also tried to change #!/bin/bash to #!/bin/sh or leave it but saddly the same result.

Also a simple case statement doesn't work:

#!/bin/sh

# use case statement to make decision
case $choose in
   "one") echo "First option.";;
   "two") echo "Second option.";;
   "three") echo "Third option.";;
   "four") echo "Fourth option.";;
   "five") echo "Fifth option.";;
   "six") echo "Last option.";;
   *) echo "Sorry, no parameter found!";;
esac

root@Omega-FAF7:~# sh case.sh "one"
: not foundne 2:
case.sh: line 4: syntax error: unexpected word (expecting "in")

Do I need to install something for using this statements?

Thanks in advance.

[György Farkas]

@Glenn-De-Vriendt Hmm. This script runs on my Omega2 (FW v0.3.2 b232) flawlessly.

#!/bin/bash
# Basic if statement
if [ 1 = 1 ] 
then
  echo "Equal"
fi

Do I need to install something for using this statements?

My Omega2 is almost in factory state. I've only changed the passwords and installed 'nano'.

Omega2's default shell is 'ash'.
So - I think - the correct shebang is #!/bin/ash or #!/bin/sh.

[Glenn De Vriendt]

Thanks @György-Farkas

The default shell is indeed 'ash'. I changed the shebang to #!/bin/ash but I've got the same result.

[György Farkas]

@Glenn-De-Vriendt Yes. This was only a notice.

The default shell is indeed 'ash'. I changed the shebang to #!/bin/ash but I've got the same result.

I don't understand how did you get this error message:
line 36: syntax error: unexpected end of file (expecting "then")
if your script is definitely shorter has only 19 lines.

[György Farkas]

@Glenn-De-Vriendt Here you are a working "simple" case example:

#!/bin/sh

# use case statement to make decision

case $1 in
  1)
    echo "First option."
    ;;
  2)
    echo "Second option."
    ;;
  3)
    echo "Third option."
    ;;
  4)
    echo "Fourth option."
    ;;
  5)
    echo "Fifth option."
    ;;
  6)
    echo "Sixth option."
    ;;
  *)
    echo "Sorry, no parameter found!"
    ;;
esac

Thanks @György-Farkas

When I run the script, I see this:

@Glenn-De-Vriendt Let us know your case2.sh please.

[György Farkas]

@Glenn-De-Vriendt Hmm. Your 'case2.sh' file is a Windows text file where the end of line is 'CR LF' (0x0d 0x0a).

@György-Farkas
Thank you very much. I never thought of that. I'll try it and let it know. I wrote it in the editor.
