Probably, all your problem are in forgetting to put back delimiter '/'
It works for me: Code:
> cat > try.t
internal://project/squid-internal-static/icons/anthony-xpm.gif

http://www.wingware.com/css/print
http://publib.boulder.ibm.com/infoce...terwarning.css
http://www.blogger.com/img/navbar/1/corner.gif
ftp://shan.org/pdg/asd/bin.jpg
ftp://pop.ces.co.uk/qwer/gft.js
^C
>nawk -F/ '{ print $1"/"$2"/"$3; }' try.t
internal://project
http://widget.blogrush.com
http://www.wingware.com
http://publib.boulder.ibm.com
http://www.blogger.com
ftp://shan.org
ftp://pop.ces.co.uk
Code:
>sed -n -e 's|\(^.*://[a-z.-]*\)/.*|\1|p' try.t > The tag does not works. Whithout tag it works: Code:
c> sed -n 's|^.*://[a-z.-]*/|lll_|p' try.t lll_squid-internal-static/icons/anthony-xpm.gif lll_img/br.png lll_css/print lll_infoce...terwarning.css lll_img/navbar/1/corner.gif lll_pdg/asd/bin.jpg lll_qwer/gft.js > c> alias sed bash: alias: `sed' not found > which sed /bin/sed |
