This chapter covers Bash shell scripts, beginning with the task of creating a new script file. It then describes several important scripting features that help you to perform progressively more complex scripting tasks. Shell scripts are plain鈥恡ext files, so you create them in text editors such...
We will first create a dummy executable script calleddothis. All it does is execute the command which resides on the number, that was passed as an argument, in user’s history. For example, the following command will simply execute thels -acommand given that it exists in history with numb...
Finally, we use crontab to call the shell script on a regular time interval. Run crontab -e to edit your crontab file. Add the following to your crontab file: */15 * * * * /bin/bash -c "~/scripts/check_val_jailed.sh" This calls the bash script every fifteen minu...

用户登录时,bash首先自动执行系统管理员建立的全局登录script :/ect/profile。然后bash在用户起始目录下按顺序查找三个特殊文件中的一个:/.bash_profile、/.bash_login、 /.profile,但只执行最先找到的一个。 因此,只需根据实际需要在上述文件中加入命令就可以实现用户登录时自动运行某些程序(类似于DOS下的Autoexec....

The repository must have an executable file at its root with the same name as the repository or a set of precompiled binary executables attached to a release. Note When relying on an executable script, we recommend using a bash script because bash is a widely available interpreter. You may ...
If the training boot script is a .py file, train.py for example, the boot command is as follows. python ${MA_JOB_DIR}/demo-code/train.py If the training boot script is a .sh file, main.sh for example, the boot command is as follows. bash ${MA_JOB_DIR}/demo-code/main.sh...
Executing the scriptWith the script saved in our PATH environment, it still will not execute as a standalone script. We will have to assign and execute permissions for the file, as needed. For a simple test, we can run the file directly with bash. The following command shows you how to...
