It’s amazing but it’s possible to write little web server on bash shell script. Here is it’s source code:

:;while [ $? -eq 0 ];do nc -vlp 8080 -c'(r=read;e=echo;$r a b c;z=$r;while [ ${#z} -gt 2 ];do $r z;done;f=`$e $b|sed 's/[^a-z0-9_.-]//gi'`;h="HTTP/1.0";o="$h 200 OK\r\n";c="Content";if [ -z $f ];then($e $o;ls|(while $r n;do if [ -f "$n" ]; then $e "`ls -gh $n`";fi;done););elif [ -f $f ];then $e "$o$c-Type: `file -ib $f`\n$c-Length: `stat -c%s $f`";$e;cat $f;else $e -e "$h 404 Not Found\n\n404\n";fi)';done

You can download it here.

Just run it and then load web page http://192.168.0.7:8080, where 192.168.0.7 is IP address of the Linux machine you've started above mentioned bash script. You'll see links to files located in directory the script was started at. My respect to Alexey Sveshnikov.

P.S. Script was tested at Ubuntu and Debian Linux.
