I have file containing 1100 variables. Example,

LOGPATH=/some/path
VARIABLE2=someVALUE

while running source /path/to/file.properties

Only the first set number of variables are being loaded. Is there a environment property that defines how many variables can be loaded.

getconf ARG_MAX gives 2097152

++ SERVICE_DATA=/some/path/data
++ AUTO_FETCH_LIMIT=25000

echo $AUTO_FETCH_LIMIT

echo $SERVICE_DATA
    /some/path/data
echo $AUTO_FETCH_LIMIT | wc
      1       0       1

    Use set -x and examine the output Commented Oct 2, 2023 at 13:33
  • set -x shows the line is executed. ++ LOGDIR=/some/path but echo $LOGDIR still shows no results. Any variables after a specific line is not loaded. If i toggle the positions, the previously missing values are loaded, but the bottom ones are not. Commented Oct 2, 2023 at 13:48

    (a) Check for unbalanced quotes in the sourced file. (b) Take out the first 50 lines (in a copy of the file), and see if it fails at the same line, or the same line number. (c) Use declare -p varName for debug, not echo. Commented Oct 2, 2023 at 14:31

    there should be an off-line version of shellcheck.net that you could run on the command line to sanity-check the sourced script (it might notice e.g. those unbalanced quotes) Commented Oct 2, 2023 at 15:28

    There is no "variable load limit". The source comand isn't for loading variables; it's for script execution. The contents of the file are executed; if it contains nothing but assignments, then it loads variables. Commented Oct 2, 2023 at 19:08
