HeadColor

Rust learning project, creates a binary file that works similar to head on linux machines, but we add color to specified column.

Instalation:

1. Clone the repo
2. Build with: cargo build --release
3. The executables will be in FileParsingTools/target/release directory

Usage:

head_color -file_name -column_number -delim -number_of_rows_to_show

Example:

head_color my_file.txt 2 "," 5

Will show first 5 rows including the header; all elements in the second column will be colored green. The delimiter is needed for the function to know where the columns are.

Using col_counter:

rustc head_color.rs
sudo mv col_counter /usr/bin

Usage:

col_counter -file_name -column_number -delim -top_n_most_common_items

Example:

col_counter my_file.txt 2 "," 5

Will display ranks, and counts corresponding to 5 most frequently occuring items.

Using set_func:

Only applies to two files that have single columns.

rustc set_func.rs
sudo mv set_func /usr/bin

Usage:

set_func -file_1_name -file_1_name -function_type

function_type:

-u <- union
-i <- intersection
-d <- difference

Example: To print the results:

set_func file_1.txt file_2.txt -u

To pipe the results to another file

set_func file_1.txt file_2.txt -u > file_3.txt
