Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Shell 脚本编写
概述
Bash 脚本编写、调试、最佳实践等技能。
基础语法
脚本结构
#!/bin/bash
# 脚本描述
# Author: name
# Date: 2024-01-01
set -euo pipefail # 严格模式
# 变量定义
VAR="value"
readonly CONST="constant"
# 主逻辑
main() {
echo "Hello, World!"
}
main "$@"
变量
# 定义变量
name="value"
name='literal value' # 不解析变量
# 使用变量
echo $name
echo ${name}
echo "${name}_suffix"
# 默认值
${var:-default} # 未设置时使用默认值
${var:=default} # 未设置时赋值并使用
${var:+value} # 已设置时使用 value
${var:?error message} # 未设置时报错
# 字符串操作
${#var} # 长度
${var:0:5} # 子串
${var#pattern} # 删除前缀
${var%pattern} # 删除后缀
${var/old/new} # 替换
数组
# 定义数组
arr=(a b c d)
arr[0]="first"
# 访问数组
${arr[0]} # 第一个元素
${arr[@]} # 所有元素
${#arr[@]} # 数组长度
${!arr[@]} # 所有索引
# 遍历数组
for item in "${arr[@]}"; do
echo "$item"
done
流程控制
条件判断
# if 语句
if [[ condition ]]; then
commands
elif [[ condition ]]; then
commands
else
commands
fi
# 条件表达式
[[ -f file ]] # 文件存在
[[ -d dir ]] # 目录存在
[[ -z "$var" ]] # 变量为空
[[ -n "$var" ]] # 变量非空
[[ "$a" == "$b" ]] # 字符串相等
[[ "$a" != "$b" ]] # 字符串不等
[[ $a -eq $b ]] # 数字相等
[[ $a -lt $b ]] # 小于
[[ $a -gt $b ]] # 大于
# 逻辑运算
[[ cond1 && cond2 ]] # 与
[[ cond1 || cond2 ]] # 或
[[ ! cond ]] # 非
循环
# for 循环
for i in 1 2 3 4 5; do
echo $i
done
for i in {1..10}; do
echo $i
done
for ((i=0; i&2
exit 1
}
# 确认函数
confirm() {
read -p "$1 [y/N] " response
[[ "$response" =~ ^[Yy]$ ]]
}
if confirm "Continue?"; then
echo "Proceeding..."

# 读取用户输入

read -t 10 -p "Quick! " answer # 超时
# 读取文件
while IFS= read -r line; do
echo "$line"
done file # 覆盖
command >> file # 追加
command 2> error.log # 错误输出
command > file 2>&1 # 合并输出
command &> file # 同上
# 输入重定向
command &2; }
die() { error "$*"; exit 1; }
# Usage
usage() {
cat
Options:
-h, --help Show this help message
-v, --verbose Enable verbose mode
Examples:
$SCRIPT_NAME -v input.txt
EOF
}
# Parse arguments
parse_args() {
while [[ $# -gt 0 ]]; do

# Your logic here
log "Starting $SCRIPT_NAME"
}

故障排查
| 问题 | 解决方法 | |------|----------| | 语法错误 | bash -n script.sh 检查 | | 变量未定义 | 使用 set -u 或 ${var:-} | | 空格问题 | 变量加引号 "$var" | | 管道错误被忽略 | 使用 set -o pipefail | | 调试困难 | 使用 set -x 或 shellcheck |
