Difference Between GAWK and AWK

GAWK vs AWK

Writing a programme using Pascal or C languages may be at times confusing. However, writing a programme becomes so easy with AWK, which is a special-purpose programming language. While using C or Pascal, it needs several lines of codes whereas AWK uses only a few lines of codes. GAWK is the GNU implementation of AWK.
GAWK is a powerful GNU version of AWK. Both the GAWK and AWK help in writing codes with ease without any worries about the overhead required for making the program. Both AWK and GAWK offer many added features which helps in quickly writing powerful programs. When using GAWK and AWK, you are free from looking into the tiresome details that makes the job of writing programmes tough. The features, such as, associative arrays, pattern-matching, and automatic handling of command-line argument files help in a better way for writing a programme in an easy way.

AWK helps in managing small and personal databases, generate reports, produce indexes, validate data, and perform other document preparation tasks. It also helps in experimenting with algorithms that can be adapted to other languages. GAWK also comes with all of these features. Apart from these features, GAWK has some additional features that make it easy for sorting data, extracting bits and pieces of data for processing, and also helps in performing simple network communications.

AWK is the name that has been derived from the initials of the designers of this programme; Alfred V. Aho, Peter J. Weinberger, and Brian W. Kernighan. The original AWK version was written in 1977 at the AT&T Bell Laboratories. It was in 1986 that GAWK was written by Paul Rubin. In 1986, Jay Fenlason completed writing GAWK.

  1. I was hoping to differences between oawk, awk, nawk, xpg4-awk, and gawk, besides the author and release dates.

    Some gawk proprietary extensions (including sockets) are really useful, but only the most simple SVID and POSIX awk scripts run under gawk.

    It would be nice to find a listing of the SVID and POSIX features that are broken under gawk.
