Synchronous copying of #在当前目录把liushanlin/down data according to the original relative path

Cat assembly.txt|  while read i;  Do ' liushanlin/ ' ' {print $} ' ' /[^/]*$ ' ' {print $} ' " finished: $i \t$b " >>rsync.log;done

2. Parse path get file name and directory name

Get file name

#awk解法: Use "/" to make the delimiter, then print out the last part.

" / " ' {print $NF} "'

#官方解法 (basename): The Bash shell itself provides the basename command to get the file name of the pathname directly.

Resfile= ' Basename/tmp/csdn/zhengyi/test/adb.log '

Get directory Name

#awk解法: You can use the flexible delimiter to mix regular expressions.

' /[^/]*$ ' ' {print $} "'

Method of #awk +for cycle

' begin{res= ""; fs= "/";} {for (i=2;i<=nf-1;i++) res= (res "/" $i);} End{print res}'

#官方解法 (basename): The Bash shell itself provides the dirname command, which is especially handy to get the directory name of the path directly.

Dirpath= ' Dirname/tmp/csdn/zhengyi/test/adb.log '
