shell 命令批量跑python代码

一、编写shell文件
假设我这里需要重复跑 testt.py 每次只需要改变传参

新建 shell 文件 命名为 my_shell.sh

1.编写shell脚本如下（作用：顺次保存每个python运行结果到文件中）

#!/bin/bash
commands=(
    "python testt.py --graph_dir './h5/var20_purity/purity_0.6'"
    "python testt.py --graph_dir './h5/var20_purity/purity_0.65'"
)
output_files=(
    "./var20_purity_out/var20_purity0.6.txt"
    "./var20_purity_out/var20_purity0.65.txt"
)
# for cmd in "${commands[@]}"; do
#     $cmd
# done

for i in "${!commands[@]}"; do
    echo "Executing command: ${commands[$i]}"
    eval "${commands[$i]}" | tee "${output_files[$i]}"
done

2.编写shell脚本如下（作用：需要把所有结果集中输出到某一个文件时）

#!/bin/bash
commands=(
    "python testt.py --graph_dir './h5/var20_purity/purity_0.6'"
    "python testt.py --graph_dir './h5/var20_purity/purity_0.65'"
)
output_files=(
    "./var20_purity_out/var20_purity0.6.txt"
    "./var20_purity_out/var20_purity0.65.txt"
)
# for cmd in "${commands[@]}"; do
#     $cmd
# done

# 创建 example.txt 文件并清空内容
echo "" > h5_reault.txt

for i in "${!commands[@]}"; do
    echo "Executing command: ${commands[$i]}"
    eval "${commands[$i]}" | tee -a h5_reault.txt "${output_files[$i]}"
done

二、运行shell的命令

bash my_shell.sh > output.txt 2>&1 &

这样就可以在output.txt 中查看在运行哪一条命令了，如果你想直接控制台看运行到哪一条直接bash my_shell.sh

如果报格式错误，运行以下命令来修复换行符格式：
sed -i 's/\r$//' run_commands.sh
