简单的项目规模统计方法

因为工作的需要，花了一点点时间做了一个关于项目规模统计的shell脚本，共大家分享。

#/bin/bash

 

do_scale()

{

       echo 'Probe *.h, *.hpp, *.cc, *.c, *.cpp files, please wait ...'

       MY_FILES=`find $1 | egrep -v 'Linux_LIB' | egrep '*/.h$|*/.hpp$|*/.c$|*.cpp$|*/.cc$' | sort`

       echo '...Done!'

       # Clear dumping file

       if [ -f ./scale.dump ]; then

              mv ./scale.dump ./scale.dump.bak

       fi

       printf "Name" >> ./scale.dump

       MY_CHARS=`printf "Name" | wc -m`

       MY_CHARS=$((32-MY_CHARS))

       while [ $MY_CHARS -gt 0 ]; do

              printf " " >> ./scale.dump

              MY_CHARS=$((MY_CHARS-1))

       done

       printf "Lines" >> ./scale.dump

       MY_CHARS=`printf "Lines" | wc -m`

       MY_CHARS=$((32-MY_CHARS))

       while [ $MY_CHARS -gt 0 ]; do

              printf " " >> ./scale.dump

              MY_CHARS=$((MY_CHARS-1))

       done

       printf "Whole Path/n" >> ./scale.dump

       set -- $MY_FILES

       MY_TOTAL_FILE_NUMS=$#

       MY_TOTAL_FILE_LINE_NUMS=0

       while [ $# -gt 0 ]; do

              MY_FILE_LINE_NUMS=`cat $1 | wc -l`

              echo "$1: $MY_FILE_LINE_NUMS lines"

              MY_TOTAL_FILE_LINE_NUMS=$((MY_TOTAL_FILE_LINE_NUMS+MY_FILE_LINE_NUMS))

              MY_FILE_LINE_NUMS=`echo $MY_FILE_LINE_NUMS | tr -d ' '`

              # Dump it

              MY_FILE_NAME=`basename $1`

              printf "$MY_FILE_NAME" >> ./scale.dump

              MY_CHARS=`printf "$MY_FILE_NAME" | wc -m`

              MY_CHARS=$((32-MY_CHARS))

              while [ $MY_CHARS -gt 0 ]; do

                     printf " " >> ./scale.dump

                     MY_CHARS=$((MY_CHARS-1))

              done

              printf "$MY_FILE_LINE_NUMS" >> ./scale.dump

              MY_CHARS=`printf "$MY_FILE_LINE_NUMS" | wc -m`

              MY_CHARS=$((32-MY_CHARS))

              while [ $MY_CHARS -gt 0 ]; do

                     printf " " >> ./scale.dump

                     MY_CHARS=$((MY_CHARS-1))

              done

              printf "$1/n" >> ./scale.dump

              shift 1

       done

       echo "Total Files     : $MY_TOTAL_FILE_NUMS"

       echo "Total file lines: $MY_TOTAL_FILE_LINE_NUMS"

       echo "Total Files     : $MY_TOTAL_FILE_NUMS" >> ./scale.dump

       echo "Total file lines: $MY_TOTAL_FILE_LINE_NUMS" >> ./scale.dump

}

 

do_help()

{

       echo "[Usage]: $0 path"

}

 

# Check and setup path

if [ $# -eq 0 ]; then

       MY_PATH=`pwd`

       echo "No path and use current path: $MY_PATH"

elif [ $# -eq 1 ]; then

       MY_PATH=$1

else

       echo 'Unsupport multi-paths'

       do_help

       exit 1

fi

 

# Check whether path is valid

if [ ! -e $MY_PATH ]; then

       echo "$MY_PATH does not exist"

       exit 2

fi

 

if [ ! -d $MY_PATH ]; then

       echo "$MY_PATH is not directory"

       exit 3

fi

 

# Do scale

do_scale $1

存在的几个问题，不知道如何解决？
1）对于计算字符串的方法，这些代码被重用过多次，所以我希望能够放在一个类似于函数中，只要输入对应不同的参数来控制，但是现在因为$1会被冲掉，所以代码看上去很脏。
2）在linux下面，有什么工具可以识别函数。

请有网友多多帮助，谢谢！

对于上次所说的第一个问题，我在学习bash的帮助后，得到解决，请看下面的代码
#/bin/bash

原来的很脏的代码，现在被简单的被printf的格式控制给替换，速度也提高了很多！"%-32.32s"重的‘－’表示左对齐，如果去掉‘－’，则为右对齐。
