You could always use an if condition checking whether the path exists, and run the script from there : if [[ -f /home/user/stuff ]]; do script if running on linux else script if running on windows fi Here the -f flags is a bash condition checking whether the file...
while read -r line; do COMMAND; done < input.file 通过-r 选项传递给 read 命令以防止阻止解释其中的反斜杠转义符。 在read 命令之前添加 IFS= 选项,来防止首尾的空白字符被去掉。 while IFS= read -r line; do COMMAND_on $line; done < input.file 这是更适合人类阅读的语法: #!/bin/bash input...

Using POSIX features only (such as in dash, which acts as /bin/sh on Ubuntu), there is no robust way to determine if a script is being sourced - see below for the best approximation. Important: The solutions determine whether the script is being sourced by its caller, which may be a ...
Like SPACE, but scrolls a full screenful, even if it reaches end-of-file in the process. ENTER or RETURN or ^N or e or ^E or j or ^J Scroll forward N lines, default 1. The entire N lines are displayed, even if N is more than the screen size. ...
Checking concatenation success: After concatenation, the script checks the exit status ($?) to determine if the operation was successful ($? -eq 0). If successful, it prints a message indicating successful concatenation; otherwise, it prints a failure message. ...
我有一个简单的bash脚本,它从命令中提取一个值,将其存储在一个变量中,并使用if条件中断构建。这在任何bash终端上都有效。请看下面的代码。 #!/bin/bash jq --version PRkey=$(curl -u TOKEN: 'https://xx.yyy.zzz/abc/abc' | jq '.pullRequests | sort_by(.key)[0].status.qualityGateStatus') ...
Bash attempts to determine when it is being run by the remote shell daemon, usually rshd. If bash determines it is being run by rshd, it reads and executes commands from ~/.bashrc, if that file exists and is readable. It will not do this if invoked as sh. The --norc option may...
By using the "test" command, the script can quickly and easily determine whether the file exists or not. The script outputs a message indicating the result of the check, and can be run as a standalone sh file or included in a larger bash script. This simple but powerful bash file demon...
local size=$(du -b "$log_file" | cut -f1) # Check if the size exceeds the maximum size if [ "$size" -gt "$max_size" ]; then echo "Log file $log_file exceeds maximum size, rotating..." # Determine the next available log file name ...
