### Create Bash script

You may simple use the following code to save as a bash script to clear docker log.

```sh
#!/bin/bash -e

if [[ -z $1 ]]; then
    echo "No container specified"
    exit 1
fi

if [[ "$(docker ps -aq -f name=^/${1}$ 2> /dev/null)" == "" ]]; then
    echo "Container \"$1\" does not exist, exiting."
    exit 1
fi

log=$(docker inspect -f '{{.LogPath}}' $1 2> /dev/null)
truncate -s 0 $log
```

### Usage

Use `docker ps` to list each docker container and find their id's.

```sh
$ docker ps
```

Clear docker log by provide docker name as first parameter of the script.

```sh
$ ./docker-clear-log my-nginx-container
```
