将运行进程扩展到ubuntu

Question

您可以从Ubuntu的终端中使用BASH脚本。如果将脚本保存为文件名“ proc.sh”，请从命令行

bash proc.sh

Answer 1

#!/bin/bash

# Define output CSV file name
OUTPUT_FILE="processes.csv"

# Create/overwrite the file with headers
echo "PID,USER,CPU%,MEM%,VSZ,RSS,TTY,STAT,START,TIME,COMMAND" > $OUTPUT_FILE

# Get process information and append to CSV file
# We use ps aux and then replace spaces with commas using awk
ps aux | tail -n +2 | awk '{
    # Store the command (which might contain spaces)
    command = ""
    for (i=11; i<=NF; i++) {
        if (command != "") command = command " "
        command = command $i
    }
    
    # Replace any commas in the command with spaces to prevent CSV issues
    gsub(",", " ", command)
    
    # Print the data in CSV format
    printf "%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,\"%s\"\n", 
           $2, $1, $3, $4, $5, $6, $7, $8, $9, $10, command
}' >> $OUTPUT_FILE

echo "Process information has been written to $OUTPUT_FILE"
