Answer 1

I used notepad++ to convert the line endings.

Answer 2

You can use sed -i 's/\r$//' scriptname.sh

Replace the scriptname with actual script name.

Answer 3

I had the same error and what I did was to transform the characters '\r' to '\n'. using this line:

tr '\r' '\n' < oldfile.sh > newfile.sh
mv newfile.sh oldfile.sh
chmod +x oldfile.sh
./oldfile.sh

I think you could also delete the '\r' characters by using:

tr -d '\r' < oldfile.sh > newfile.sh

tr is the command trasnform, and the -d is delete the following character.

I think the shell actually doesn't like '\r' character.

Answer 4

I had this exact issue when creating a .sh file on a Mac (unix) and executing it in Linux. Turns out that I had to set FileZilla FTP settings to 'Binary' transfer type:

• "Settings>Transfers>File Types>Default transfer type" to "Binary" (instead of "Auto")

Answer 5

Your problem is that the file has Windows line endings. This can be caused by editing a file in Windows and trying to run it on a non-Windows system.

You can fix this problem using dos2unix to convert the line endings:

dos2unix ConstruedTermsXMLGenerator.sh

The corresponding utility to convert in the other direction is unix2dos.

Some systems have fromdos and todos.

Answer 6

I got a different error message when running your script under /bin/sh, but when I switched to /bin/bash, it worked fine:

$ cat foo.sh
#!/bin/sh
if [[ $# -lt 1 ]];
    then echo "ERROR Environment argument missing"
    RC=50
    exit $RC
fi
$ sh foo.sh
foo.sh: 6: [[: not found
$ bash foo.sh
ERROR Environment argument missing

You've built in a bashism. This may or may not be a big deal for your organization. If you want to keep using bash-specific features, change the shebang line to #!/bin/bash and see if that helps.
