Tar-cvf xboing.tar-T test
Gzip xboing.tar
Cp xboing.tar.gz/mnt/usb
The above command can copy a software which have been installed on someone system to your own system ^-^
#! /Bin/sh
For fname in *; do
Tmp = 'echo $ fname | tr [a-z] [A-Z] '# note, tr can't act like this 'tr fname [a-z] [A-Z]'
# It must run as this 'tr # So, if you want rename a file list, you must redirect tr's stdin to some command's stdout
Mv $ fname $ tmp
Done
The above code cost me lots of time! ^-^
