问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . My boss has a habit of performing queries on our databases that return tens of thousands of rows and saving them into excel files.

问题 How can I make this code work? #!/bin/bash ARRAYNAME='FRUITS' FRUITS=( APPLE BANANA ORANGE ) for FRUIT in ${!ARRAYNAME[@]} do echo ${FRUIT} done This code: echo ${!ARRAYNAME[0]} Prints APPLE . I'm tryng to do something similar but with "[@]" to iterate over the array. Thanks in advance, 回答1: ${!ARRAYNAME[@]} means "the indices of ARRAYNAME ". As stated in the bash man page since ARRAYNAME is set, but as a string, not an array, it returns 0 . Here's a solution using eval . #!/usr/bin/env bash

问题 I'm creating an installation script for an application that I'm developing and need to create databases dynamically from within PHP. I've got it to create the database but now I need to load in several .sql files.

问题 I'm developing a web game in pure Python, and want some simple scripting available to allow for more dynamic game content. Game content can be added live by privileged users. It would be nice if the scripting language could be Python. However, it can't run with access to the environment the game runs on since a malicious user could wreak havoc which would be bad. Is it possible to run sandboxed Python in pure Python? Update : In fact, since true Python support would be way overkill, a simple

问题 I have a variable in my bash script whose value is something like this: ~/a/b/c Note that it is unexpanded tilde. When I do ls -lt on this variable (call it $VAR), I get no such directory. I want to let bash interpret/expand this variable without executing it. In other words, I want bash to run eval but not run the evaluated command. Is this possible in bash? How did I manage to pass this into my script without expansion? I passed the argument in surrounding it with double quotes. Try this
