about upper case file name to low case , Thanks

Unix1998

Hi Dear Dxs,
Chinese input was damaged, sorry

a one line script , to change upper case files name to low case
files name, can't run correctly:
in current dir:
ls | xargs mv  $1 `echo $1| tr '[A-Z]' '[a-z]'`,

it is asked to use "xargs", do't use the below:
for i in "dir";
do mv $i  `echo $1| tr '[A-Z]' '[a-z]'`



Any help,

Thanks  a lot,

john_student

mymv.sh:
=============

mv $1 `echo $1 | tr '[A-Z]' '[a-z]'`

=============

cmd :
chmod 755 mymv.sh

ls | xargs ./mymv.sh
=============

sorry, it does not work .

这样如何？BTW:觉得楼主的例子不适合用xargs.

1. ls -1|grep '[A-Z]'|xargs sh -c 'for i;do mv $i `echo $i|tr A-Z a-z`;done' null

不用循环的话，只用xargs很难实现楼主的要求。
