shell - How to select files in a directory begins with explicit names in bash? -

i have shell script below

dcachedirin="/mypath/" files in `ls $dcachedirin | grep txt` ..... done 

i have .txt files in directory, of them begins data2012*.txt , of data2011*.txt. how can choose "data2012" files?

edit: bad mixed python file. shell script sure.

you can try this

dcachedirin="/mypath/" files in `ls $dcachedirin | grep data2012` echo $files done 

to avoid directories name, try

ls $dcachedirin -p | grep -v / | grep data2012
