Script test failing
Testing some old script developed by different user.
Code:
#!/usr/bin/sh
case "$0" in
  */*) cmd="$0";;
  *) cmd=`which "$0"`;;
esac
dir=`dirname "$cmd"`
node="$dir/."
echo $node

below two simple tests are failing, I am not seeing any Control+M characters in the script file and I am not able to understand error from second test.

First test:
Code:
$ ./usernames.sh
-bash: ./usernames.sh: /usr/bin/ksh^M: bad interpreter: No such file or directory

Second test:
Code:
$ sh -x usernames.sh
'sernames.sh: line 2: syntax error near unexpected token `in
'sernames.sh: line 2: `case "$0" in

I appreciate any help.

Thanks in advance

Markar

The error says you are using incorrect ksh path in the first line...but your script shows you are using sh

type the below command and use the first relust in the script

Code:
$ whereis sh
sh: /bin/sh /sbin/sh /usr/share/man/man1p/sh.1p.gz /usr/share/man/man1/sh.1.gz
$ cat usernames.sh
#! /bin/sh
case "$0" in
*/*) cmd="$0";;
*) cmd=`which "$0"`;;
esac
dir=`dirname "$cmd"`
node="$dir/."
echo $node
$

The errors show that you have edited your shell script with an editor that replaced the UNIX <newline> line terminators with the Windows <carriage-return><newline> line terminators. Get rid of the <carriage-return> characters and you might have better luck. Unfortunately, it is also VERY clear that the errors you showed us from the shell did not come from the shell script you showed us; so there is no way to know if that is your only problem.
Code:
cp usernames.sh _usernames.sh && tr -d '\r' < _usernames.sh > usernames.sh

Followed your suggestion and now script is running successfully.

Thanks
