awk + fit syntax for SUN solaris & linux

Question

hi all

need help about the following

when I run the following command on linux its run fine

  awk -v NAME=MACHINE '$1 == NAME'  /etc/hosts 

but on SUN Solaris I get the following:

 awk -v NAME=MACHINE '$1 == NAME'  /etc/hosts 
 awk: syntax error near line 1
 awk: bailing out near line 1

how to fit the following syntax in order to fit also SUN Solaris? or change in order to fit both on linux and SUN Solaris

Answer 1

Solaris is well known for the fact that the some commands under /bin /usr/bin are not POSIX compliant. Instead they have additional compliant versions under /usr/xpg4 and similar hierarchies.

Thus, under Solaris you can use just:

/usr/xpg4/bin/awk -v NAME=MACHINE '$1 == NAME'  /etc/hosts 

Under Solaris 10 this works.

Answer 2

the simple way is to use nawk and the rest syntax
