# -f <file> Execute file on host, print the result and exit

# -c <command> Execute command on host, print the result and exit
|

# -v <level> Verbose mode: 1 - verbose, 2 - super verbose

## Example disabling option:
|
|
#if [[ $EXECUTE_COMMAND ]]; then
|
|
# echo '<THIS> entrypoint is not support command execution.'
|
|
# exit 1
|
|
#fi
|
|
|
|
## Example command argument:
|
|
#if [[ $EXECUTE_COMMAND ]]; then
|
|
# EXECUTE_COMMAND=(-c "${EXECUTE_COMMAND}")
|
|
#fi
|
|
#
|
|
#if [[ $EXECUTE_FILE ]]; then
|
|
# EXECUTE_COMMAND=""
|
|
#fi
|
|
|
|
## Example of adding argument `-f` before
|
|
#EXECUTE_FILE=`[ $EXECUTE_FILE ] && echo -n "-f $EXECUTE_FILE" || echo -n ""`
|
|
#
|
|
|
|
#
|
|
# Move to current directory
|
|
#
|
|

|
|
cd $CURRENT_DIR
|
|
|
|
export XXH_HOME=`realpath -m $CURRENT_DIR/../../../../`

# Run the portable shell

# Example:
