Shell腳本統計文件行數

轉自 http://www.jb51.net/article/61943.htm 

 

示例：row_count.sh文件

awk '{print NR}' row_count.sh | tail -n1

awk 'END{print NR}' row_count.sh

grep -n "" row_count.sh|awk -F: '{print '} | tail -n1

sed -n '$=' row_count.sh

wc -l row_count.sh

cat row_count.sh | wc -l

一、獲取指定目錄所有文件的行數：

#!/bin/bash filesCount=0 linesCount=0
function funCount() { for file in ` ls $1 ` do
        if [ -d $1"/"$file ];then funCount $1"/"$file
        else declare -i fileLines fileLines=`sed -n '$=' $1"/"$file` let linesCount=$linesCount+$fileLines let filesCount=$filesCount+1
        fi
    done } if [ $# -gt 0 ];then
    for m_dir in $@ do funCount $m_dir done
else funCount "."
fi
echo "filesCount = $filesCount"
echo "linesCount = $linesCount"

使用方法：

1、針對本目錄

./count.sh

2、統計多個目錄

./count.sh /tmp ~

二、獲取指定目錄特定擴展名文件的行數

#!/bin/bash

extens=(".c" ".cpp" ".h" ".hpp")
filesCount=0
linesCount=0
function funCount()
{
    for file in ` ls $1 `
    do
        if [ -d $1"/"$file ];then
            funCount $1"/"$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
        fi
    done
}

if [ $# -gt 0 ];then
    for m_dir in $@
    do
        funCount $m_dir
    done
else
    funCount "."
fi
echo "filesCount = $filesCount"
echo "linesCount = $linesCount"

使用方法：

1、針對本目錄

./count.sh

2、統計多個目錄

./count.sh /tmp ~
