loop shell for beginners

i'm new in shell programming.
let say i have this file in directory
file1.txt.
file2.txt
sample1.txt
sample2.txt

so,i want to move file that begin with name"file" to another directory.so how is it?
help me please

Dude, you don´t have to write a programme to do this. These jobs can usually be done on the command line. I don´t have a unix terminal handy, so I can´t test these commands, but to move all the files beginning with ´file´into the directory ´/tmp´ you need to use something like:

ls -al | grep "file" | xargs mv /tmp

or to run recursively. use the find command with exec:

find . -name "file*" -exec mv /tmp {} \;

Note, I havn´t tested these, so have a play on some dummy files & directories first
