about upper case file name to low case , Thanks 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, about upper case file name to low case , Thanks mymv.sh: ============= mv $1 `echo $1 | tr '[A-Z]' '[a-z]'` ============= cmd : chmod 755 mymv.sh ls | xargs ./mymv.sh ============= about upper case file name to low case , Thanks sorry, it does not work . about upper case file name to low case , Thanks 这样如何？BTW:觉得楼主的例子不适合用xargs. [code]ls -1|grep '[A-Z]'|xargs sh -c 'for i;do mv $i `echo $i|tr A-Z a-z`;done' null[/code] about upper case file name to low case , Thanks 不用循环的话，只用xargs很难实现楼主的要求。 [ 关闭窗口 ]
