curl -sSi <URL> | sed '/^\r$/q'

User: cbuckley
Functions: sed
Tags: curl http

Similar to the following:

curl -I <URL>

but curl -I performs a HEAD request, which can yield different results.

aria2c -x 4 http://my/url

User: lx45803

jrk's aria2 example is incorrect. -s specifies the global connection limit; the per-host connection limit is specified with -x.

(echo -e "HTTP/1.1 200 Ok\n\r"; tail -f /var/log/syslog) | nc -l 1234
2013-02-09 06:15:42
User: adimania
Functions: echo tail

This one is tried and tested for Ubuntu 12.04. Works great for tailing any file over http.

tcpdump -s 1024 -l -A -n host
2013-02-02 22:29:52
User: wejn
Functions: host tcpdump
Tags: http tcpdump

This is a better way to do the "src X or dst X" filter; plus you might not want to bother with DNS lookups (-n).

tcpdump -s 1024 -l -A src or dst
2013-02-01 15:03:12
User: bleiva
Functions: tcpdump
Tags: http tcpdump

Where src or dst is the host that you want to view the HTTP header.

curl -L -d "uid=<username>&pwd=<password>" http://www.example.com -c cookies.txt

Generate a Netscape cookies file to use with Python's mechanize.

apache2 -l
httpd -M

Easiest way to check which modules are loaded in apache.

curl -s "$URL" |wc -c
2011-07-18 15:47:57
User: Mozai
Functions: wc
Tags: size curl http

Downloads the entire file, but http servers don't always provide the optional 'Content-Length:' header, and ftp/gopher/dict/etc servers don't provide a filesize header at all.

curl -Is google.com | grep Date
2011-06-24 11:19:47
User: d3Xt3r
Functions: grep
Tags: http date time

This command will show the current GMT time using HTTP. This might be useful if you just want to know what's the current human-readable and accurate-enough time, without changing the system time, using a simple command that would work regardless of the availability of NTP.

Note: To get a quicker and more accurate response, replace google.com with your local NTP server.

Also can be used as an alternative to the "htpdate" program:


tshark -i en1 -z proto,colinfo,http.request.uri,http.request.uri -R http.request.uri
curl -I http://localhost
for file in `cat urls.txt`; do echo -n "$file " >> log.txt; curl --head $file >> log.txt ; done
2010-10-19 02:54:13
User: Glutnix
Functions: echo file

urls.txt should have a fully qualified url on each line

prefix with

rm log.txt;

to clear the log

change curl command to

curl --head $file | head -1 >> log.txt

to just get the http status

curl -L -s `curl -s http://www.2600.com/oth-broadband.xml` | xmlstarlet sel -t -m "//enclosure[1]" -v "@url" -n | head -n 1` | ssh -t [user]@[host] "mpg123 -"

Ever wanted to stream your favorite podcast across the network, well now you can.

This command will parse the iTunes enabled podcast and stream the latest episode across the network through ssh encryption.

tcpdump -i eth0 port 80 -w -
curl -s -L --head -w "%{http_code}\n" URL | tail -n1

Validates and pretty-prints the content fetched from the URL.

aria2c -s 4 http://my/url

User: jrk

`aria2c` (from the aria2 project) allows. Change -s 4 to an arbitrary number of segments to control the number of concurrent connections. It is also possible to provide multiple URLs to the same content (potentially over multiple protocols) to download the file concurrently from multiple hosts.

curl -i -X HEAD http://localhost/
