Remove “\r” from echoing out in bash script

Question

Here is my bash script that is sent a variable from php:

STRING1="/opt/lampp/htdocs/dev/img/$VAR1"
mv $STRING1 "/opt/lampp/htdocs/dev/newlocation/"

It, for some reason, places "\r" at the end of $STRING1 and can't find the file because it will be something of the form "my_picture.jpg\r"

Any help is appreciated!

Answer 1

Bash expects that end-of-line in a script is always and only a newline (\n) character, Unix-style, not a carriage return-newline combination (\r\n) like you normally see on Windows. Bash thinks the \r character is just an ordinary character at the end of the string. (Characters that follow a double quoted string are just concatenated onto the end.)

As Ignacio suggests, the solution is to fix your script to eliminate the \r characters. dos2unix is one way. Another would be to use tr -d '\r' < infile > outfile as a filter.

Answer 2

Pass the script through dos2unix to fix the newlines.
