I would like to rename the pics i'm shooting (from the same script) but i'm unsure of how to go about it without string manipulations.
i need a way to determine if a file has been processed or not. the first method to come to mind is to check whether the file starts with IMG. But I don't think there's a way to analyze substrings without the strings lib.
---
background on how i'm going about this.
running a loop and the first action inside that loop is to check for files that need renaming. then i check to see if a pic has been taken at this minute yet. if not, shoot.
