I think this is the worst error I have ever seen. I have written what I have seen also here:
Example of script but continuously I get error. My plan is to see how read command works. But it seems a dodgy error in my code or terminal. I wondered if anyone has seen similar problem?
#!/usr/bin/bash
echo "Plz enter"
read text
echo "You entered $text"
echo $text
echo "$text"
Error:
$ . test.sh
Plz enter
b
': not a valid identifier
You entered
$
Yes I had the same error in windows with cygwin, I fixed it changing the end of line format from windows format to unix format.
You can also convert the end of line format using Notepad++: Edit > EOL Conversion > UNIX, then save and run the file.
Your input file contains CR+LF line endings.
Remove those and the script should work well. You could use dos2unix or any other utility to remove the CR.
I think, try to change the shell path as like below!
root@sathish:/tmp# vim test.sh
#!/usr/bin/bash
echo "Plz enter"
read text
echo "You entered $text"
echo $text
echo "$text"
root@sathish:/tmp# chmod +x test.sh
root@sathish:/tmp# ./test.sh
-bash: ./test.sh: /usr/bin/bash: bad interpreter: No such file or directory
root@sathish:/tmp# which bash
/bin/bash
root@sathish:/tmp# ls /usr/bin/bash
ls: cannot access /usr/bin/bash: No such file or directory
root@sathish:/tmp# vim test.sh
#!/bin/bash
echo "Plz enter"
read text
echo "You entered $text"
echo $text
echo "$text"
root@sathish:/tmp# ./test.sh
Plz enter
a
