Question
1. Create a sub directory “cs232hw7” under your home directory
2. Download all https://github.com/aws/aws-iot-device-sdk-embedded-C/ sub directories under cs232hw7
3. Write a shell script to do the following Find out all unique .h files included in all *.c files, and save the output in a file called “includeheaders.txt” with one .h file per line (Unix commands grep, sort, and uniq may be useful) For each .h file in includeheaders.txt, list the number of *.c file including .h file, and save the output in a file called “headerInclusionNumber.txt” with one .h file per line e.g. stdio.h 20 (Unix command grep may be useful)
include shell script file, includeheaders.txt , and headerInclusionNumber.txt
Explanation / Answer
shell script:
#!/bin/sh
find /home/prashanth/Desktop/cs232hw7 -name "*.h" -print >> headers.txt
tr '/' ' ' < headers.txt >delimitedHeaderFiles.txt
awk '{print $NF}' delimitedHeaderFiles.txt > onlyHeaderFiles.txt
sort onlyHeaderFiles.txt | uniq -u > includeheaders.txt
while read p; do
count=$(grep -r --include *.c $p . | wc -w)
echo $p $count >> headerInclusionNumber.txt
done < includeheaders.txt
