# Debugging
|
||
|
|
|
||
|
|
Debugging is vital for efficient Bash scripting.
|
||
|
|
|
||
|
|
### Debugging Your Scripts
|
||
|
|
|
||
|
|
Troubleshoot your Bash scripts by tracing execution. Use `-x` directly or `set -x` for specific sections.
|
||
|
|
|
||
|
|
Run your script with `bash -x` to see every command executed:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
bash -x ./your_script.sh
|
||
|
|
```
|
||
|
|
|
||
|
|
For targeted debugging, use `set -x` where you want to start tracing, and `set +x` to stop.
|
||
|
|
|
||
|
|
Create `debug_example.sh`:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
touch debug_example.sh
|
||
|
|
```
|
||
|
|
|
||
|
|
Open `debug_example.sh` and add:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
#!/usr/bin/env bash
|
||
|
|
|
||
|
|
echo "Starting script."
|
||
|
|
set -x # Enable debug mode from here
|
||
|
|
ls -l
|
||
|
|
my_variable="test_data"
|
||
|
|
echo "Variable is: $my_variable"
|
||
|
|
set +x # Disable debug mode
|
||
|
|
echo "Debugging finished."
|
||
|
|
```
|
||
|
|
|
||
|
|
Save, make executable, and run:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
chmod +x debug_example.sh
|
||
|
|
./debug_example.sh
|
||
|
|
```
|
