What output are you getting?
What output do you want to get?
With no indication of what you are trying to do and no indication of the state of the conditions being tested by your script, it is hard to guess at what you might think right or wrong?
Ah my bad, I am trying to detect the file to see if it existed, but cannot have it run indefinitely, so I've put the counter as a limit
using || or &&, the counter still went beyond 10, in which I expect after trying to detect the file 10 times, the script will quit

Hi!
Can anyone explain this? The counter CDR_count should go on forever, but it suddenly resets at every step of the FOR loop (I know this because $_file has exactly 378 records). However, the counter reset is OUTSIDE the FOR loop. What's going on??

NAME
script - make record of a terminal session
SYNOPSIS
script [-a] [filename]
DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
record is saved in the file typescript. See WARNINGS.
The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
when the forked shell exits or when Control-d is typed.
OPTIONS
The following option is supported:
-a Appends the session record to filename, rather than overwriting it.
NOTES
script places everything that appears on the screen in filename, including prompts.

WARNINGS
script can pose a security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
privileged user, that is, root. Be sure that typescript is not a link before running script.
