wget, login & cookie

If you need to sign into a site and download a file automatically with wget, here is a shell script for that:

<br /> #!/bin/sh</p> <p>COOKIE_FILE=cookie.txt<br /> LOGIN_URL=”http://example.com/login?username=xxxx&password=xxxx”</p> <p>login() {<br /> echo “Signing in….”<br /> wget –save-cookie cookie.txt $LOGIN_URL<br /> return<br /> }</p> <p>print_usage() {<br /> echo “Usage: $0 [URL]”<br /> return<br /> }</p> <p>if [ $# -eq 0 ] ; then<br /> print_usage<br /> exit 1<br /> fi</p> <p>if [ ! -r $COOKIE_FILE ] ; then<br /> login<br /> fi</p> <p>wget –load-cookie cookie.txt “$1” -O output.file<br />
