Usage Instructions

This repository contains three files: srep, repl_l, and repl_c, each designed to perform specific text manipulation tasks akin to commonly used Linux commands.

How to Use:

#Go to the Directory
#where you can find install.sh
#Open terminal and run these commands

chmod u+x install.sh &&  ./install.sh

bash Usage: srep pattern [options] [file ....] 

srep is a versatile script that mimics the functionality of the grep command in Linux. It searches for a specified pattern in one or more files and outputs lines or highlights the words containing the pattern.

Options:

• -i : Ignore case distinctions.
• -w : Match whole words only.
• -c : Display count of matching lines.
• -n : Display line numbers along with matching lines.

bash Usage: repl_l linenumber "string" file

repl_l is a script designed to replace a line in a specified file at a given linenumber with the provided "string".

Usage: repl_c file "string1" "string2"

repl_c allows users to replace occurrences of "string1" with "string2" in the specified file.

Example Usage:

• To search for the pattern "example" in a file named sample.txt ignoring case distinctions and displaying line numbers:

  srep -i -n "example" sample.txt

• To replace line number 5 in file.txt with the string “Hello World”:

  repl_l 5 "Hello World" file.txt

• To replace occurrences of "old" with "new" in data.txt:

  repl_c data.txt "old" "new"

Please ensure you have appropriate permissions to execute these scripts and provide valid inputs as specified in the usage instructions.

For more details on each command's usage and options, refer to the respective script files.

Note: These scripts are designed for basic text manipulation tasks and may not encompass the full functionality of their counterparts in the Linux environment. Feel free to modify and extend them according to your requirements.
