SHELL SCRIPT BELOW

https://www.dropbox.com/s/eb6zrofbhjdgbe4/grep.zip?dl=0

The attached zip file contains a shell script that works with a file named rgb.txt that should be in your /home/ascuser home directory. Upload to zip file to your virtual machine and unzip it (see man unzip). Make sure that the file grep-prob.sh is executable (chmod +x grep-prob.sh). When run, it will display:

There are 10 egrep regular expression patterns to be entered in place of "pattern" to select the indicated lines from the rgb.txt file. Read the comments preceding the egrep lines carefully to determine what the required pattern should match. When all 10 patterns are complete, zip up your completed script as assign2.zip, download it and post it to this assignment. The completed script output should look like:

What I got / PROGRAM:

#!/bin/bash

# one of the methods for digital color specification is with red, green, and blue values (RGB),

# each value is 8 bits long with a range of 0 to 255. The file rgb.txt has lines with the format:

# color_name = #rrggbb

# where rr, gg, and bb are each 2 hexadecimal digits (8 bits)

#

# in the following, use egrep to match the specified pattern.

#

ln=0

tmp=tfile

ct=

export ct

### find all the colors that have "green" in the name

egrep "green" rgb.txt | tee $tmp;ct=`wc <$tmp -l`

echo "$((++ln)). --- $ct"

### find all the colors that have 00 red and green components

egrep "pattern" rgb.txt | tee $tmp;ct=`wc <$tmp -l`

echo "$((++ln)). --- $ct"

### find all the colors whose name begins with "blue..."

egrep "blue" rgb.txt | tee $tmp;ct=`wc <$tmp -l`

echo "$((++ln)). --- $ct"

### find all the colors that have a red value of 0x87

egrep "pattern" rgb.txt | tee $tmp;ct=`wc <$tmp -l`

echo "$((++ln)). --- $ct"

### find all the colors that have the fruits orange, papaya, peach, or plum in their name

egrep "orange, papaya, peach, plum" rgb.txt | tee $tmp;ct=`wc <$tmp -l`

### find all the color names that start with "light" and end with "yellow"

egrep "pattern" rgb.txt | tee $tmp;ct=`wc <$tmp -l`

### is there any color with the word "host" in its name?

egrep "host" rgb.txt | tee $tmp;ct=`wc <$tmp -l`

echo "$((++ln)). --- $ct"

### find all the colors that have equal red and blue components

egrep "pattern" rgb.txt | tee $tmp;ct=`wc <$tmp -l`

echo "$((++ln)). --- $ct"

### find all the colors that have only one 00 color component

egrep "pattern" rgb.txt | tee $tmp;ct=`wc <$tmp -l`

echo "$((++ln)). --- $ct"

### find all the colors that have equal RGB components

egrep "pattern" rgb.txt | tee $tmp;ct=`wc <$tmp -l`
