I am trying to replace a string which is currently output as


so that it will only output as


I am using SED to replace a URL with the latter domain but I'm unable to get it to work. It works if I set "domain1" to be replaced by "domain2" however I want to be able to replace the whole string.

I'm trying to do this will the following code:

for FILE in `cat/WORKDIR/$inputControlFileName`; do sed -i -e  "s~$SEARCHTEXT~$REPLACEWITH~g" $OutputDirectory/$FILE; done;

My search parameter is http://domain1.com/subdomain/http://domain2.com/subdomain and replace parameter is http://domain2.com/subdomain

Appreciate any guidance.

Update Thanks you all for your help, I ended up getting this to work by only outputting domain1.com/domain.2.com and then escaping the values stored in the variables.

  • why don't we truncate the first domain?

Try this,

echo "http://domain1.com/subfolder1/http://domain2.com/subfolder2" | sed 's/^http.*http:/http:/'
  • But what if the URL contains http as a subfolder name?

  • good catch.... hope we can overcome by suffixing second http with colon

    Seems right. Something like | sed 's/^http:\/\/.*http\:\//http:\/\//g' would do the trick. I can also suggest awk: | awk -F'http://' '{print "http://" $NF}'

If you never have : in the URI, you can do this only using bash builtins.

function last_addr(){
    echo -n http:; echo ${array[-1]}; unset IFS

last_addr 'http://domain1.com/subfolder1/http://domain2.com/subfolder2'
  • Thanks, your comment about never having : gave me the solution.
