After making the corrections to the variable names as suggested above, please re-test and then post the complete script in code tags (including the SQL bit) because there is no way that the error message containing "[[" came from the script posted in post #1.
Also, please stop putting semi-colons at end of Shell command lines. This is unix Shell not SQL.
Most of the typing errors in your script have been addressed. Just to make clear another poster's point:
Should be using double quotes not single quotes. Within single quotes the $ variables are not expanded, within double quotes the $ variables are expanded. Also the variable name ${FILE_NAME} appears to be correct in the "echo" statement but incorrect in the actual "cp" statement.
Quote:
cp ${FILE_NAME} ${LIS_FILE_PATH} ${LIS_FILE_NAME}
In additon to the typing errors in the names of the variables, your "cp" line is missing a solidus.
Also the variable ${LIS_FILE_NAME} should probably be ${FILE_NAME}. Hard to tell for definite without seeing the whole script.
The /CODE tag terminator is missing from your CODE tags in your post.
Hello. Complete newbie over here, and I'm hoping you can help me out with this problem.
The script copies a file to a directory within my home dir.
Permissions are ok and the source file exists. If I execute the cp command from the command line or hardcode the path/file name, it works.

need to be able to capture a file with the following conditions:
The filenames are, for example, 3526_332840.dat, where 3526 is constant, and 332840 is a sequential number which is always a couple hundred greater than the previous day's file.

bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
