SO - Test Shell

1. citeste numere cu stdin, afiseaza cele intregi si pozitive, face suma celor > 3 cifre, scrie in file daca e fisier obisnuit
testare_numar_intreg_pozitiv ()
{
	if test $1 -ge 0
	then
		echo $1
	fi
}

if test $# -ne 1
then
	echo "wrong number of arguments"
	exit -1
fi

file=$1
sum=0

if [ ! -h $file ] && [ -f $file ]
then
	while read linie && test "$linie" != "End"
	do
		testare_numar_intreg_pozitiv $linie
		if test ${#linie} -ge 3
		then
			sum=`expr $sum + $linie`
		fi
	done

	echo "suma = $sum" > $file
else
	echo "not regular file"
	exit -2
fi





2. citeste cu stdin, daca e director, parcurge nerecursiv si numara legaturile simbolice care incep cu majuscula si nu au cifra in nume, scrie in file daca e fisier normal
if test $# -ne 1
then
	echo "wrong number of arguments"
	exit -1
fi

file=$1
contor=0

if [ ! -h $file ] && [ -f $file ]
then
	while read linie && test "$linie" != "Stop"
	do
		if test -d $linie
		then
			echo $linie
			for f in $linie/*; do
    				if test -h $f
				then
					if [[ "$(basename -- $f)" =~ ^[A-Z][^0-9]*$ ]];
					then
						contor=`expr $contor + 1`
					fi
				fi
			done
			echo "$linie: $contor legaturi" >> $file
			contor=0
		fi
	done
else
	echo "not a regular file"
	exit -2
fi



3. ia un file si un prefix. citeste de la tastatura pana la 'End'. numara toate cuvintele care incep cu prefix si face suma lungimilor tuturor cuvintelor. afiseaza contorul si suma la fiecare pas, las final scrie suma in file.
if test $# -ne 2
then
	echo "wrong number of arguments"
	exit -1
fi

file=$1
prefix=$2
contor=0
suma=0

if [ ! -h $file ] && [ -f $file ]
then
	while read linie && test "$linie" != "End"
	do
		if [[ "$linie" =~  ^$prefix ]];
		then
			echo $linie
			contor=`expr $contor + 1`
		fi
		suma=`expr $suma + ${#linie}`
		echo "contor = $contor"
		echo "suma = $suma"
	done
	echo "suma = $suma" >> $file
else
	echo "not a regular file"
	exit -2
fi
