poor mans watch, watch for solaris

Here is a simple script that you can use as watch in Solaris as well.

Rekursive Grep on Solaris or AIX Systems without GNU egrep -r funcionality

If you work regularly on a Solaris or systems which do not have the “-r” (recursive grep) for grep, then you know what a lifesaver this command can be.

Here is one from command line fu:

find . -type f -exec awk '/linux/ { printf "%s %s: %s\n", FILENAME, NR, $0; }' {} \;

The benefit of using awk here is that you can print the line number also 🙂

Add ssh key to remote host

If you are working on recent versions of the *nix OS like Fedora or Ubuntu then you would know about the commad ssh-copy-id. But if you land up using one of the older versions like Solaris or something where the command is not present, then probably you need a simpler solution to this. One of the simplest solution is with a lot of assumtions, simply copy the id_rsa file to remote server and hope it works. And here is  a script to do just that:

install all solaris software from http

If you are behind a firewall and install some software like top or wget then you can not use sunfreeware, and why because ftp is blocked. Now that is not the case any more, you can go the http mirror site of sunfreeware and here is the link for the same

http://ftp.sunfreeware.com/ftp/pub/freeware/i386/5.10/

Note: you just need to change the words in bold for sparc or i386 and version of the solaris.

\[Solution\] Solaris issue with wget not resolving Domain name (DNS name lookup failure)

Today I was working with <a class="zem_slink" title="Solaris (operating system)" rel="homepage" href="http://oracle.com/solaris">Solaris and after I had set up the <a class="zem_slink" title="NIS+" rel="wikipedia" href="http://en.wikipedia.org/wiki/NIS%2B">NIS+, <a class="zem_slink" title="Name server" rel="wikipedia" href="http://en.wikipedia.org/wiki/Name_server">DNS server, IP Address and completing the basic setting. I was using the pkg-get util from the freesunware.com

From the looks of it, it was very clear that the wget utility was unable to find the <a class="zem_slink" title="IP address" rel="wikipedia" href="http://en.wikipedia.org/wiki/IP_address">IP address from the name. <a class="zem_slink" title="Name resolution" rel="wikipedia" href="http://en.wikipedia.org/wiki/Name_resolution">Name resolution was not happening, while dig and <a class="zem_slink" title="Nslookup" rel="wikipedia" href="http://en.wikipedia.org/wiki/Nslookup">nslookup was able to do the DNS lookup.
