Get the number of rows for all files in a particular directory

The code is as follows:

Copy Code code as follows:

#!/bin/bash

Filescount=0
Linescount=0
function Funcount ()
{
For file in ' ls $ '
Todo
If [-D $/$file];then
Funcount "/" $file
Else
Declare-i Filelines
filelines= ' sed-n ' $= ' $ '/' $file '
Let linescount= $linesCount + $fileLines
Let filescount= $filesCount +1
Fi
Done
}

If [$#-gt 0];then
For M_dir in $@
Todo
Funcount $m _dir
Done
Else
Funcount "."
Fi
echo "Filescount = $filesCount"
echo "Linescount = $linesCount"

How to use:

1, for this directory

{
For file in ' ls $ '
Todo
If [-D $/$file];then
Funcount "/" $file
Else
Filename=$1 "/" $file

Extension= "." ${filename##*.}
echo "FileName = $fileName Extension = $EXTENSION"

            if [[${extens[@]/$EXTENSION/} "!=" ${extens [@]}" ]]; Then
                declare-i Filelines
                filelines= ' sed-n ' $= ' $fileName '
                 echo $fileName ":" $fileLines
                 let linescount= $linesCount + $fileLines
                 let filescount= $filesCount +1
             fi
