In Linux, I have many files and I need to copy paste the mth word of the nth line of all the files onto a plain .txt file along with the file names. So my final text file looks somewhat like this...
在Linux中，我有很多文件，我需要将所有文件的第n行的第m个字复制粘贴到一个普通的.txt文件中以及文件名。所以我的最终文本文件看起来有点像......
<FileName1> <mth word of nth line of FileName1>
<FileName2> <mth word of nth line of FileName2>
.
.
<FileNameN> <mth word of nth line of FileNameN>
Can someone please let me know the Linux command for this. Thanking you!!

#!/bin/sh
if [ "$#" != 3 ]
then
echo "$0 [dir] [lineno] [wordno]"
exit
fi
rm -f a.txt
dir=$1
lineno=$2
wordno=$3
while read -u3 file
do
read -a words < <(tail -n+$lineno $file)
echo $file ${words[wordno-1]} >> a.txt
done 3< <(find $dir -type f)

How about using awk?
用awk怎么样？
#!/bin/bash
# Usage: <line> <word> <files...>
awk "NR==$1 { print FILENAME \" \" \$$2 }" "${@:3}"
