我有这样一个文件:

This is a file with many words.

this@1
is@1
a@1
file@1
with@1
many@1
words3
some@2
of@2
the@2
only@1
appear@2
more@1
than@1
one@1
once@1
time@1

sed -i "s/ /\n/g" ./file1.txt # put all words on a new line
while read line
do
     count="$(grep -c $line file1.txt)"
     echo $line"@"$count >> file2.txt # add word and frequency to …
