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.
I had added directory browse support:
:;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 $b|sed “s#^/##g;s#/$”"##g”`;h=”HTTP/1.0″;o=”$h 200 OK\r\n”;c=”Content”;if [ -z "$f" -o -d "$f" ];then($e $o;$e “Parent Directory“;if [ $f ];then f=$f/;fi;cd “$f”;ls|(while $r n;do if [ -e "$n" ]; then $e “`ls -ghd $n`“;fi;done););cd ->/dev/null;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 $f\n”;fi)’;done
Tested on Ubuntu 8.04.
Ooops, system removed all tags in the code. Here is another try:
:;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 $b|sed “s#^/##g;s#/$”"##g”`;h=”HTTP/1.0″;o=”$h 200 OK\r\n”;c=”Content”;if [ -z "$f" -o -d "$f" ];then($e $o;$e “Parent Directory“;if [ $f ];then f=$f/;fi;cd “$f”;ls|(while $r n;do if [ -e "$n" ]; then $e “`ls -ghd $n`“;fi;done););cd ->/dev/null;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 $f\n”;fi)’;done
I’m sorry for repeat comments. This must be displayed correctly:
:;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 $b|sed "s#^/##g;s#/$""##g"`;h="HTTP/1.0";o="$h 200 OK\r\n";c="Content";if [ -z "$f" -o -d "$f" ];then($e $o;$e "<a href=\"/`dirname "$f"`\">Parent Directory</a><br>";if [ $f ];then f=$f/;fi;cd "$f";ls|(while $r n;do if [ -e "$n" ]; then $e "<a href=\"/$f$n\">`ls -ghd $n`</a><br>";fi;done););cd ->/dev/null;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 $f\n";fi)’;done

Good work Erdem Güven! But you didn’t add just the directory browse support, now you can see every file you have on you computer, not just the ones you put in the same folder where the script is.
Try looking at http://localhost:8080///etc/passwd
This should give you an idea about what I’m trying to explain…
