如何在 Linux 中的进程列表中隐藏脚本?

如何在 Linux 中的进程列表中隐藏脚本?

我在linux下有一个脚本:

#!/bin/bash
export DISPLAY=:1
value=$(</home/pace/Desktop/BODVersion.txt)
cd $value
gnome-terminal \
        --tab -t "CTCLManager" -e " sh -c 'sleep 1s; ./startapp CTCLManager' "\
        --tab -t "SMM" -e " sh -c 'sleep 10s; ./startapp SMM' "\
        --tab -t "ClientCommunicator" -e " sh -c 'sleep 20s; ./startapp ClientCommunicator' "\
        --tab -t "GATS" -e " sh -c 'sleep 30s; ./startapp GATS' "\

我的问题是,一旦我在服务器 (GUI) 上运行此脚本并w从 CLI 在同一服务器上发出命令,就会得到以下输出:

[root@demo ~]# w
 12:23:27 up  8:22, 10 users,  load average: 4.12, 2.92, 1.75
USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT
root     pts/0    192.168.0.100   11:43    0.00s  0.00s  0.00s w
pace     pts/1    :1               12:16    6:39   2.38s  0.00s sh -c sleep 1s; ./startapp CTCLManager
pace     pts/2    :1               12:16    6:39   0.05s  0.00s sh -c sleep 10s; ./startapp SMM
pace     pts/3    :1               12:16    6:39   0.20s  0.00s sh -c sleep 20s; ./startapp ClientCommunicator
pace     pts/5    :1               12:16    6:39  12:52   0.00s sh -c sleep 30s; ./startapp GATS
[root@demo ~]#

我不想在 中显示此内容w,请帮助我在 的输出中隐藏我的脚本w

让我们考虑一个简单的脚本:

[09:37] [vhost0 ~] # cat script.sh
echo "sleeping..."; sleep 100.

我运行它,检查第二个终端,这是我看到的:

[09:37] [vhost0 ~] # w
 09:36:42 up 17:20,  2 users,  load average: 0.06, 0.03, 0.00
USER     TTY      FROM             LOGIN@   IDLE   JCPU   PCPU WHAT
root     pts/0    192.168.56.1     Wed20    2.00s  0.07s  0.00s sleep 100
root     pts/1    192.168.56.1     09:08    0.00s  0.09s  0.01s w

但接下来我们修改脚本:

[09:40] [vhost0 ~] # cat script.sh
secretcommand() { echo "sleeping..."; sleep 100; }

echo SECRET | secretcommand

检查w...

[09:36] [vhost0 ~] # w
 09:40:40 up 17:24,  3 users,  load average: 0.00, 0.00, 0.00
USER     TTY      FROM             LOGIN@   IDLE   JCPU   PCPU WHAT
root     pts/0    192.168.56.1     Wed20    8.00s  0.10s  0.00s bash script.sh
root     pts/1    192.168.56.1     09:08    0.00s  0.09s  0.00s w

当然,这并不是说我们完全隐藏了您的存在,但仍然向您的父母隐瞒了您的肮脏秘密;)

UPD

更新后的脚本应如下所示:

#!/bin/bash
export DISPLAY=:1
value=$(</home/pace/Desktop/BODVersion.txt)
cd $value
secretcommand() {
        gnome-terminal \
                --tab -t "CTCLManager" -e " sh -c 'sleep 1s; ./startapp CTCLManager' "\
                --tab -t "SMM" -e " sh -c 'sleep 10s; ./startapp SMM' "\
                --tab -t "ClientCommunicator" -e " sh -c 'sleep 20s; ./startapp ClientCommunicator' "\
                --tab -t "GATS" -e " sh -c 'sleep 30s; ./startapp GATS' "\;
}

echo SECRET | secretcommand
