So I have a very simple bash script that is curl'ing to an auth server for a header. The header url is written to a var and then used in the next curl call. When using the var set in the first curl call I am getting "curl: (3) Illegal characters found in URL". I am able to echo the var and all looks good, I am even able to reset the var (in my example below) and it works.
The Bash script
URL=$(curl -i -X GET -H "X-Auth-User: MyUserna,e" -H "X-Auth-Key: MyAPIKey" "https://urlToAuthServer.tld/auth/v1.0/" | grep "X-Storage-Url:" | awk '{print $2}') curl -X GET -H "X-Auth-Token: MyAuthTok" "${URL}/folder/myfile.txt" -o ./myfile.txt When running the above example I get:
curl: (3) Illegal characters found in URL The URL var looks like this (no illegal chars)
https://somesecureurl.com/auth/AUTH_67383834-45245453-g34g34t5-34534 When I do this in terminal it works:
$ URL=$(curl -i -X GET -H "X-Auth-User: MyUserna,e" -H "X-Auth-Key: MyAPIKey" "https://urlToAuthServer.tld/auth/v1.0/" | grep "X-Storage-Url:" | awk '{print $2}')
$ echo $URL
https://somesecureurl.com/auth/AUTH_67383834-45245453-g34g34t5-34534
Now I copy and paste the string and reasign it to URL like so (again all in terminal):
>$ URL="https://somesecureurl.com/auth/AUTH_67383834-45245453-g34g34t5-34534" >$ curl -X GET -H "X-Auth-Token: MyAuthTok" "${URL}/folder/myfile.txt" -o ./myfile.txt It works.
So why am I getting the "curl: (3) Illegal characters found in URL" error in the first example?
Update I ran this: printf %s "$URL" | xxd
Here is the output (addressed changed up you get the idea)
