A Bash script is used to obtain command line parameters of the running programs.

proc

#!/bin/bash

# Check whether the command line parameters are provided. 
# If not, display the usage and exit
if [ $# -ne 1 ]; then
    echo "Usage: $0 <process_name>"
    exit 1
fi

# Get the process name to find from the command line parameters
process_name="$1"

# Use PGREP to find all the matching PIDs, 
# and check the command line parameters one by one
for pid in $(pgrep $process_name); do
    cmdline=$(cat /proc/$pid/cmdline 2>/dev/null | tr '\0' ' ')
    if [ -n "$cmdline" ]; then
        echo "PID: $pid, Command Line: $cmdline"
    fi
done
