How do I make my Bash script run faster?
There are few ways to make your shell (eg Bash) execute faster. Try to use less of external commands if Bash’s internals can do the task for you. Eg, excessive use of sed , grep , awk et for string/text manipulation. If you are manipulating relatively BIG files, don’t use bash’s while read loop.
Is Perl faster than awk?
On this planet, simpler and faster is better! Perl or Python are far better than any version of awk or sed when you have very complex input/output scenarios. Actually as Perl was designed to encompass both Sed and Awk; I find it easier to just write it in Perl, rather than learning Sed or Awk.
Is Perl faster than bash?

Is shell script faster?
Bash is the default user shell on every Linux distribution you know about as well as macOS, which makes it relatively faster than Python in terms of performance. Bash is the default user shell on every Linux distribution you know and on macOS.
Why awk is faster than Python?
Also, awk is way faster than Python. Its patterns aren’t interpreted over and over like they would be in Python; they’re compiled into a state machine. Python regexes can be saved into variables, and even if you don’t do it manually it automatically maintains a pattern-cache for the last expressions you have used.
Why is awk so useful?
awk is most useful when handling text files that are formatted in a predictable way. For instance, it is excellent at parsing and manipulating tabular data. It operates on a line-by-line basis and iterates through the entire file. By default, it uses whitespace (spaces, tabs, etc.) to separate fields.
