ShellPal-shell command explanations

Example

Explain the command `ls -l | grep '^d'`.

Scenario

A user wants to list all directories in the current folder using a command but doesn't fully understand the components. ShellPal explains that `ls -l` lists files in long format, and `grep '^d'` filters out entries that start with 'd', indicating directories.

Example

Clarify the syntax of `for i in {1..10}; do echo $i; done`.

Scenario

A user is learning loop constructs in bash and needs clarification on the syntax used in a for loop. ShellPal breaks down the loop structure, explaining the sequence generation `{1..10}`, the loop variable `i`, and the commands executed within the loop.

Example

Provide use cases for the `awk` command.

Scenario

A user is familiar with the `awk` command but wants to see practical examples. ShellPal provides examples like extracting specific columns from a text file (`awk '{print $1, $3}' file.txt`) or performing calculations on data (`awk '{sum+=$1} END {print sum}' file.txt`).
