Is Shell Scripting difficult?

Shell scripting is not particularly difficult for those with the prerequisites. No experience with the underlying commands available — if you don’t know how to use the individual tools nor even what problems they solve then it is of course difficult to put them together in a script.

Is shell scripting necessary?

Using a shell script is most useful for repetitive tasks that may be time consuming to execute by typing one line at a time. A few examples of applications shell scripts can be used for include: Automating the code compiling process. Running a program or creating a program environment.

if you know very little about the linux utilities and regex and stuff. then i expect it taking around 6 months or so with regular practice to become pretty competent at bash.

What coding language should I learn first?

Python is always recommended if you’re looking for an easy and even fun programming language to learn first. Rather than having to jump into strict syntax rules, Python reads like English and is simple to understand for someone who’s new to programming.

What is the difference between Grep and AWK?

These ‘pattern-matching’ commands can contain regular expressions as for grep. The awk commands can do some quite sophisticated maths and string manipulations, and awk also supports associative arrays. AWK sees each line as being made up of a number of fields, each being separated by a ‘field separator’.

How does grep work in Linux?

In the simplest terms, grep (global regular expression print) will search input files for a search string, and print the lines that match it. Beginning at the first line in the file, grep copies a line into a buffer, compares it against the search string, and if the comparison passes, prints the line to the screen.

Does AWK support Substitution commands as well?

For example: I know the sed commands to make the changes I just wanted a way to peform them on lines starting with “employee”. Maybe awk supports substitution commands as well – sub to replace first occurrence and gsub to replace all occurrences.

Should I use GSUB or GSUB with AWK?

Maybe awk supports substitution commands as well – sub to replace first occurrence and gsub to replace all occurrences. Also allows to change only specific field You really do not need to use both tools, either will do everything you need. Thanks for contributing an answer to Stack Overflow!
