Need this in an hour

You are tasked with writing a script that will find all the C function given a directory. Your script will have to recursively look through the directory and find all .c files and output the functions contained within them.

Given the directory structure:

Your code should retrieve all functions from:
* mysql_bridge.c
* postgres_bridge.c
* main.c
* db_adapter.c

Your script should output "Unable to find any functions" if no source files were encountered.
Specifically, the only source files that should be search for are .c files (headers are ignored)

This will be an opportune time to utilise regular expressions in your script. Your task should execute within Ed's linux environment. If it fails to execute properly, you will receive no marks for this task.

Your script requires using taking a command line argument which should be the root of the project.

Example 1:

Example 2: Bad directory

Example 3: Unable to find functions

Explanation / Answer

CODE:

findfn.sh

if [ $# -ne 1 ]

then

echo "USGAE: $BASH_SOURCE <project folder>"

exit 1

fi

Dir=$1

count=0

## if directory is passed

if [ -d "${Dir}" ] ; then

Files=`find $Dir -name "*.c"`

# for each C files in directory.

for file in $Files

do

echo $file

echo `grep -r "^(w+) +w+ *([w,-*]*)" $file`

temp_count=`grep -r "^(w+) +w+ *([w,-*]*)" $file | wc -l`

count=`expr $count + $temp_count`

done

if [ $count -eq 0 ]

then

echo "unable to find any funntions"

fi

else

echo "$Dir is not a directory"

OUTPUT:

$ ./findfn.sh ~/temp/

/home/rojindal/temp/main.c

int main()
