how to install package

Hi

How to install package from Freeware for Solaris
Specificaly i want to install lsof-4.77-sol10-sparc-local.gz

Thanks
Amit

unzip using gzip -d lsof-4.77-sol10-sparc-local.gz
in the same dir you unzzipped it, then execute pkgadd -d . pkg name

Actually:
gunzip package-file.gz # equivalent to "gzip -d"
pkgadd -d package-file
