How to get file creation date/time in Bash/Debian?

Unfortunately your quest won't be possible in general, as there are only 3 distinct time values stored for each of your files as defined by the POSIX standard (see Base Definitions section 4.8 File Times Update)

Each file has three distinct associated timestamps: the time of last data access, the time of last data modification, and the time the file status last changed. These values are returned in the file characteristics structure struct stat, as described in <sys/stat.h>.

EDIT: As mentioned in the comments below, depending on the filesystem used metadata may contain file creation date. Note however storage of information like that is non standard. Depending on it may lead to portability problems moving to another filesystem, in case the one actually used somehow stores it anyways.

mikyra's answer is good.The fact just like what he said.

[jason@rh5 test]$ stat test.txt  File: `test.txt'  Size: 0               Blocks: 8          IO Block: 4096   regular empty fileDevice: 802h/2050d      Inode: 588720      Links: 1Access: (0664/-rw-rw-r--)  Uid: (  500/   jason)   Gid: (  500/   jason)Access: 2013-03-14 01:58:12.000000000 -0700Modify: 2013-03-14 01:58:12.000000000 -0700Change: 2013-03-14 01:58:12.000000000 -0700

if you want to verify wich file was created first,you can structure your file name by appending system date when you create a series of files.
