有没有办法杀死多个进程？例如

kill -9 49855 49856

我尝试过使用类似的命令，pkill但它们需要一个模式并且不允许多个 pid 输入。

kill

我正在尝试删除数 TB 的文件夹，并希望看到这些内容实际上已被删除。目前，该命令

find . -name "labelled_point_clouds" -type "d" -exec rm -r {} +

没有显示任何内容，我将等待几天不知道它是否在做某事。我怎样才能让命令也输出它删除的每个文件夹？

如何在不执行命令的情况下将任何命令的输出重定向到文本文件？例如，我想在运行之前确认会被压缩的文件

zip -r point_clouds.zip data/*/*/point_clouds

通过将输出写入文本文件，例如

zip -r point_clouds.zip data/*/*/point_clouds | tee test.txt

或删除操作

find . -name "*.tif" -type 'f' -size -160k | tee test.txt

我有如下所示的目录结构。我想创建一个仅包含point_clouds. 我尝试使用通配符，但它不起作用。

blender:~/data$ zip -r test.zip *point_clouds

如何仅压缩point_clouds子文件夹但保持结构相同？我不需要其他非压缩子文件夹。

data/

        sequence1/
        sequence2/

我正在尝试移动所有中间有数字 1 的文件夹(glove.6B.60d.txt)和(model)

mv "./*.txt)(1)(m*" "/home/e1"

但我收到错误消息

mv: cannot stat './*.txt)(1)(m*': No such file or directory

我究竟做错了什么？我在同一个文件夹

如何使用 ffmpeg 并排连接 5 个视频？有人也可以请解释一下命令。我只知道如何编写 python，并且很难理解更复杂的 ffmpeg 命令。例如，下面的这个脚本从左到右和从上到下连接视频，但我如何阅读命令？

ffmpeg -i input0 -i input1 -i input2 -i input3 -filter_complex \
"[0:v][1:v]hstack[top]; \
 [2:v][3:v]hstack[bottom]; \
 [top][bottom]vstack,format=yuv420p[v]; \
 [0:a][1:a][2:a][3:a]amerge=inputs=4[a]" \
-map "[v]" -map "[a]" -ac 2 output.mp4

是[0:v]指第 0 行到第 v-1 行吗？

hstack该命令应用于哪些变量[0:v][1:v]hstack[top]？为什么不是hstack(input0,input1)？

我正在尝试安装此https://github.com/NVlabs/ssn_superpixels但在步骤中收到以下错误cmake ..

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
CUDA_cublas_LIBRARY (ADVANCED)
    linked by target "caffe" in directory /home/haziq/ASTAR/scripts/ssn_superpixels/lib/video_prop_networks/lib/caffe/src/caffe

然后我尝试搜索该库并找到一个libcublas.so.9.1和libcublas.so.9.1.85.

(base) haziq@mdeep:~/ASTAR/scripts/ssncaffe$ ls /usr/lib/x86_64-linux-gnu/libcublas.so.9.1
libcublas.so.9.1     libcublas.so.9.1.85

我现在如何告诉 CMake 到 CUDA_cublas_LIBRARY 的路径？命令

cmake .. CUDA_cublas_LIBRARY=/usr/lib/x86_64-linux-gnu/libcublas.so.9.1

不工作？

我正在尝试编译此代码https://thoth.inrialpes.fr/src/deepmatching/这应该与运行make命令一样简单，但出现错误

g++：错误：/usr/lib64/atlas/libsatlas.so：没有这样的文件或目录

我在网上读到这是因为我缺少 atlas 库所以尝试运行该命令pip install atlas但仍然遇到相同的错误。我可以就如何解决这个问题获得一些建议。

我不明白为什么有些 Python 包是使用安装的，conda而有些是使用pip3.

这些只是来自不同开发人员的不同安装程序但做同样的事情吗？

我可以互换使用它们来安装 Python 包吗？

例如：

conda create -n mtl python=3.6 anaconda
conda activate mtl
conda install pytorch torchvision cudatoolkit=10.1 -c pytorch
pip3 install opencv-python
python pip conda

我是新手，所以如果我使用了错误的术语，我深表歉意。

我正在使用 Linux 并使用 ssh 功能连接到我的学校工作站。如果我运行一个程序并关闭终端，程序就会停止。我在询问 ubuntu 时读到我应该使用屏幕功能。但是，当我关闭屏幕时出现错误并且进程停止运行。我仍然可以重新连接到屏幕。

linux screen XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server "localhost:11.0"       after 4570 requests (4570 known processed) with 192 events remaining.

如果我使用命令创建了一个虚拟环境virtualenv venv然后我激活它source venv/bin/activate，我的终端现在看起来像这样

(venv) haziq@vita-workstation2:~$

安装包现在只安装在我的环境中还是全局安装？例子

pip3 install numpy

如何将多个文件夹移动到另一个目录？例如，我想将文件夹 000/ 001/ 002/ 移动到 train/000/ train/002 train/003。有没有我可以使用的简单命令

我有一个要从 shell 脚本运行的 python 代码。这个有效

python train.py --dataset './datasets/lausanne' --timestep 30 --obs_len 8 --loader_num_workers 1 --num_epochs 100 --batch_size 16 --embedding_dim 64 --h_dim 32 --num_layers 1 --mlp_dim 64 --dropout 0 --batch_norm 0 --learning_rate 0.0001 --output_dir './models' --print_every 100 --checkpoint_every 100 --checkpoint_name 'cnnlstm' --checkpoint_start_from None --restore_from_checkpoint 1 --use_gpu 1 --gpu_num '0'

但是这个没有。我只想将命令拆分为多行。

python train.py \
# Dataset options
--dataset './datasets/lausanne' --timestep 30 --obs_len 8 --loader_num_workers 1 \
# Optimization
--num_epochs 100 --batch_size 16 \

使用 rsync 时如何排除文件夹？

rsync -i /home/kong/.ssh/id_rsantu --exclude /media/kong/Elements/sgan/dataset/ /media/kong/Elements/sgan/ [email protected]:~/

这就是我得到的信息。但是我进入服务器并没有看到复制的文件。

skipping directory .
<f..T...... id_rsantu

我包括了 --exclude= 但它仍在复制，/media/kong/Elements/sgan/dataset/因为我看到了

我安装了 ubuntu 并按照指南将 20gb 放入“/”，其余（150gb）放入“/home”。现在我刚刚发现 ubuntu 中安装的很多东西通常会转到“/”而不是“/home”。我还有很多东西要安装。

那么 '/home' 有什么意义呢？我该如何解决 ？我应该将 150gb 从 '/home' 转移到 / 吗？

Filesystem      Size  Used Avail Use% Mounted on
udev            7.8G     0  7.8G   0% /dev
tmpfs           1.6G  9.5M  1.6G   1% /run

tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           7.8G     0  7.8G   0% /sys/fs/cgroup

tmpfs           1.6G   56K  1.6G   1% /run/user/1000

什么是 /boot ？它不是“/”或“/home”
