## file-checker
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
In this exercise you will make a script `file-checker.sh` that will check the status of a given file using if statements.
|
||
|
|
|
||
|
|
Your script should make the following checks:
|
||
|
|
|
||
|
|
- File exists.
|
||
|
|
|
||
|
|
- File is readable.
|
||
|
|
|
||
|
|
- File is writable.
|
||
|
|
|
||
|
|
- File is executable.
|
||
|
|
|
||
|
|
It should output the status as in the example in the usage.
|
||
|
|
|
||
|
|
You should also handle what to do when no file is provided. The use of `test` command is not allowed for this exercise.
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ ./file-checker.sh file.txt
|
||
|
|
File exists
|
||
|
|
File is readable
|
||
|
|
File is not writable
|
||
|
|
File is not executable
|
||
|
|
$ ./file-checker.sh
|
||
|
|
Error: No file provided
|
||
|
|
$
|
||
|
|
```
|
||
|
|
|
||
|
|
### Hints
|
||
|
|
|
||
|
|
[bash conditional expressions](https://www.gnu.org/software/bash/manual/html_node/Bash-Conditional-Expressions.html) can be used to solve this exercise.
|
||
|
|
|
||
|
|
For example for `script.sh`:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
#!/usr/bin/env bash
|
||
|
|
|
||
|
|
if [ -s $1] ; then
|
||
|
|
echo "File size greater than 0"
|
||
|
|
fi
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output:
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ ./script.sh file.txt
|
||
|
|
File size greater than 0
|
||
|
|
$
|
||
|
|
```
