Suggest me the easiest method
Hi,
I want to check whether a file of the format myfile_YYYYMMDD_HHMMSS.txt exists in a particular directory. Here YYYYMMDD_HHMMSS is the time stamp, so it will be numbers always [ I want to check for numbers only, no need to check whether valid time , if it is well and good ].
What is the best method to do this
I did it like this :
ls myfile_[0-9]*_[0-9]*.txt
but it will list files like myfile_YYYYDD_HH.txt etc
Regards
Shihab
