XPR is a lightweight C program designed to work with text files.
It allows you to search, replace, append, and display file contents with line numbers.

Created primarily as a learning and demonstration project to explore command-line utilities and string handling in C.

Experiment, learn and extend it! 😎

Compile the program using GCC:

gcc -o xpr xpr.c

Run it directly:

./xpr [file] [option] [arguments...]

• Display file contents with line numbers (-o)

  ./xpr sample.txt -o

• Append a string to the file (-a)

  ./xpr sample.txt -a "This is a new line"

• Search for a string in the file (-s)

  ./xpr sample.txt -s "apple"

• Replace a string and save to a new file (-r)

  ./xpr sample.txt -r "old" "new" output.txt

• Help (-h or --help)

  ./xpr -h
  ./xpr --help

• Version (-v or --version)

  ./xpr -v
  ./xpr --version
