Is awk portable?
Which is the most portable of sed, awk, perl and sh? sed , sh and awk are portable being specified by POSIX, perl is not as not being backed by a standard.
Is Perl better than sed?
Sed is the best tool for extremely simple command-line pipelines. Perl or Python are far better than any version of awk or sed when you have very complex input/output scenarios. The more complex the problem is, the better off you are using python, from a maintenance and readability standpoint.
What is awk Perl?
The Inline::Awk module allows you to include awk code in your Perl program. You can call awk functions or entire programs. Inline::Awk works by converting awk code into Perl code using the a2p utility which comes as standard with Perl. This means that you don’t require awk to use the Inline::Awk module.
Which is better for text processing awk or Perl?
Awk is a little more of a general purpose language but it is still best suited for text processing. Perl and Python are fully fledged, general purpose programming languages. Perl has its roots in text processing and has a number of awk-like constructs (there is even an awk-to-perl script floating around on the net).
What’s the difference between AWK and SH in Linux?
AWK is oriented towards text processing (it complements more specialized utilities), while sh is oriented towards being a glue language to put programs together. Sh is the universal scripting language on Linux and across the unix world.
Which is the most universal scripting language for Linux?
After bash (and sh), the next most “universal” scripting language for Linux would be some dialect of awk – usually either mawk or gawk. If you stick with plain awk and avoid gawkisms your script should run fine on almost any Linux system (it may be missing on tiny distros or embedded devices).
Which is the best awk for data reformatting?
Gawk (the GNU awk) is by far the best choice for complex data reformatting when there is only a single input source and a single output (or, multiple outputs sequentially written). Since a great deal of real-world work conforms to this description, and a good programmer can learn gawk in two hours, it is the best choice.
