Shell script throws a not found error when run from a sh file. But if entered manually the commands work

I’m trying to use the following script to generate a sitemap for my website. When I run it as sh thsitemap.sh I get an error like this and creates an empty sitemap.xml file:

thsitemap.sh: 22: thsitemap.sh: [[: not found
thsitemap.sh: 42: thsitemap.sh: [[: not found
thsitemap.sh: 50: thsitemap.sh: Syntax error: "(" unexpected

But as the same user root when I manually copy and paste these lines on the terminal, it works without any error and the sitemap.xml file have all the urls. What’s the problem? How can I fix this?

Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.

Method 1

Run the script either as:

bash script.sh

or just:

./script.sh

When bash is run using the name sh, it disables most of its extensions, such as the [[ testing operator.

Since you have the #!/bin/bash shebang line, you don’t need to specify the shell interpreter explicitly on the command line. Running the script as a command will use that line to find the shell.

Method 2

I know this is an old thread but i came across the same problem, i just did
dos2unix filename.sh (i wanted to parse a text, the sh has a ton of commands and the python it called just did a small check, every time i ran it like that i got

./teste2.sh: line 1: $’r’: command not found
./teste2.sh: line 2: $’r’: command not found
./teste2.sh: line 3: $’r’: command not found
./teste2.sh: line 4: $’r’: command not found

After using dos2unix the problem was fixed at least for me.

Method 3

Both your… if [[ debug = "...“ ]] ; then... commands are incorrect they should read…

if [ "debug" = "Y" -o "debug" = "y" ]
