I am very new to linux unix ubuntu what ever. i am running on an old: inspiron 530s, 991.5 MiB RAM, Intel® Pentium(R) Dual CPU E2160 @ 1.80GHz × 2, Intel® G33 x86/MMX/SSE2, 32-bit OS, disk 77.6 GB.

i think i would need a step by step instruction on how to create a script. to maintain a directory. it can only get so full and old files can be deleted to maintain the directory. i am using 2 easyn ip cam's and ftp into this machine. i have it forwarding to the ftp every second.

my ftp is pureftp server -- pureadmin v0.4 for gui

i made a directory in my home directory that the ftp puts the files.
/dadscam
in that directory is.
/cam1
/cam2

unless there is a program already out there i think i need a script.

thank you

i am STILL searching google. put don't see anything user friendly or step by step. sorry if i annoy you with this thread.I would like to add some info.

the picture file names go something like this:

00A00107151A(IP\ Camera\ 2)_1_20140422200106_2852.jpg
file size are approximately 50.1kb
I am using approximately 8gb out of 66gb of hard drive from 6gb in the last 12 hrs

i think i have more of a ram problem then a hard drive issue. i found this out by trying to access the cam1 directory threw the GUI. wow it stalled or lagged. but it seemed a lot easier access threw the terminal.Well i looked up some other scripts in hopes to get close too what i am looking for. so here is what i found and have.
