shell/ target=_blank class=infotextkey>shell脚本统计文件行数的8种方法
一、使用shell脚本获取单个文件行数。
文件:test1.sh
行数:20
方法一
linuxjishu/13830.html target=_blank class=infotextkey>awk '{print NR}' test1.sh|tail -n1
方法二
awk 'END{print NR}' test1.sh
方法三
grep -n "" test1.sh|awk -F: '{print '}|tail -n1
方法四
方法五
wc -l test1.sh
方法六
#cat test1.sh |wc -l
二、获取特定目录所有文件的行数
复制代码 代码示例:
#!/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 ~
二、获取特定目录特定扩展名文件的行数
复制代码 代码示例:
#!/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 ~
运行效果:
