方法一  
awk '\{print NR\}' test1.sh|tail -n1  
示例：

[root@adiislogdata164 test]# ls
    front_action.log.2015-05-13-00.log
    [root@adiislogdata164 test]# awk '{print NR}' front_action.log.2015-05-13-00.log | tail -n1
    273736
    [root@adiislogdata164 test]#

方法二  
awk 'END\{print NR\}' test1.sh

示例：

[root@adiislogdata164 test]# ls
    front_action.log.2015-05-13-00.log
    [root@adiislogdata164 test]# awk 'END{print NR}' front_action.log.2015-05-13-00.log 
    273736
    [root@adiislogdata164 test]#

方法三  
grep -n "" test1.sh|awk -F: '\{print '\}|tail -n1  
示例：

[root@adiislogdata164 test]# grep -n "" front_action.log.2015-05-13-00.log|awk -F: '{print '}|tail -n1
    273736:2015-05-13 00:59:59|@183.31.247.46|@15b55bbd-df33-4a64-9838-44ffd34a23f3|@176|@1|@44|@58|@1-39|@cn020_0756_[gd_zh]|@ent.ifeng.com|@0|@0
    [root@adiislogdata164 test]#

方法四  
sed -n '$=' test1.sh  
示例：

[root@adiislogdata164 test]# ls
    front_action.log.2015-05-13-00.log
    [root@adiislogdata164 test]# sed -n '$=' front_action.log.2015-05-13-00.log 
    273736
    [root@adiislogdata164 test]#

方法五  
wc -l test1.sh  
示例：

[root@adiislogdata164 test]# ls
    front_action.log.2015-05-13-00.log
    [root@adiislogdata164 test]# wc -l front_action.log.2015-05-13-00.log
    273736 front_action.log.2015-05-13-00.log
    [root@adiislogdata164 test]#

方法六  
cat test1.sh |wc -l

示例：

[root@adiislogdata164 test]# ls
    front_action.log.2015-05-13-00.log
    [root@adiislogdata164 test]# cat front_action.log.2015-05-13-00.log | wc -l
    273736
    [root@adiislogdata164 test]#

七、获取特定目录所有文件的行数

#!/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)针对本目录  
./count.sh  
  
2)统计多个目录  
./count.sh /tmp ~

示例：  
![Center][]

八、获取特定目录特定扩展名文件的行数

#!/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、针对本目录  
./count.sh  
  
2、统计多个目录  
./count.sh /tmp ~

示例：  
![Center 1][]
