Shell脚本统计文件行数

Shell脚本统计文件行数

转自 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、获取指定目录所有文件的行数：

#!/bin/bash 

filesCount=
linesCount=
function funCount()
{
    for file in ` ls $ `
    do
        if [ -d $"/"$file ];then
            funCount $"/"$file
        else
            declare -i fileLines
            fileLines=`sed -n '$=' $"/"$file`
            let linesCount=$linesCount+$fileLines
            let filesCount=$filesCount+
        fi
    done
}

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

使用方法：

1、针对本目录

./count.sh

2、统计多个目录

./count.sh /tmp ~

二、获取指定目录特定扩展名文件的行数

#!/bin/bash
extens=(".c" ".cpp" ".h" ".hpp")
filesCount=
linesCount=
function funCount()
{
    for file in ` ls $ `
    do
        if [ -d $"/"$file ];then
            funCount $"/"$file
        else
            fileName=$"/"$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+
            fi
        fi
    done
}

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

使用方法：

1、针对本目录

./count.sh

2、统计多个目录

./count.sh /tmp ~
