Shell编程练习

题目：利用所学知识，写一个脚本，实现一下功能：将 uboot 源码中包含的 awk 命令的文件找出来，并将它们拷贝到一个叫 awks 的目录中。

 

程序一：

 

#!/bin/bash
 
full_path_files=`grep 'awk' * -wr | awk 'BEGIN{FS=":"} {print $1}' | uniq`
 
bk="awks"
if [ ! -d $bk ]
then
       mkdir $bk
fi
 
for full_path_file in $full_path_files
do
       echo $full_path_file > files
       file_name=`awk 'BEGIN{FS="/"} {print $NF}' files`
 
       if [ -e "$bk/$file_name" ]
       then
              n=`ls $bk/$file_name* | wc -w`
              n=$(($n + 1))
              cp $full_path_file $bk/$file_name$n
       else
              cp $full_path_file $bk/$file_name
       fi
done

程序二：

#!/bin/bash
 
full_path_files=`grep 'awk' * -wr | awk 'BEGIN{FS=":"} {print $1}' | uniq`
bk="awks"
 
if [ ! -d $bk ]
then
       mkdir $bk
fi
 
for full_path_file in $full_path_files
do
       if [ $full_path_file != collect_awk.sh ]
       then
              echo $full_path_file > files
              file_name=`sed 's/\//#/g' files`
              cp $full_path_file $bk/$file_name
       fi
done
