Copied from iesaya idea's(script for writing scripts) but for a simple 'Hello, World!' C program..
Note: the gcc compiler requires the source code file name to have an extension .c
Code:
#! /bin/sh
echo -n "enter filename->"
read myfile
creatit()
{
exec 3>>$1
echo "#include <stdio.h>">&3
echo "#include <stdlib.h>">&3
echo >&3
echo "int main(int argc, char**argv)">&3
echo "{">&3
echo " fputs(\"Hello, World!\\n\", stdout);">&3
echo " exit(EXIT_SUCCESS);">&3
echo "}">&3
exec 3>&-
mypos=`expr index $1 .`#get the position of .c from the filename
mypos=`expr $mypos - 1`#so we can strip it out
if gcc $1 -Wall -ansi -pedantic -o ${1::$mypos}>/dev/null 2>&1 \
&& echo -n "do you want to execute->(y/n)"
then
read ans
if [ "$ans" = "y" ]
then
./${1::$mypos}
fi
else
echo "'$1' failed to compile"
exit 1
fi
}
if [ -f "$myfile" ]
then
echo -n "'$myfile' already exists - overwrite->(y/n)"
read ans
if [ "$ans" = "y" ]
then
rm -f $myfile
creatit $myfile
else
echo "exiting program"
exit 1
fi
else
creatit $myfile
fi
exit 0
