passing password to curl on command line
You can use:
curl -u abcuser:trialrun https://xyz.abc.compIn your script:
curl -u ${user}:${pass} ${url}To read from stdin:
curl https://xyz.abc.com -K- <<< "-u user:password"When using -K, --config specify - to make curl read the file from stdin
That should work for HTTP Basic Auth, from the curl man:
-u, --user <user:password> Specify the user name and password to use for server authentication.
To expand on @nbari's answer, if you have a tool "get-password" that can produce a password on stdout, you can safely use this invocation:
user="abcuser"url="https://xyz.abc.com"get-password $user | sed -e "s/^/-u $user:/" | curl -K- $urlThe password will be written to a pipe. We use sed to massage the password into the expected format. The password will therefore never be visible in ps or in the history.
