How do you assign the value of a parameter to a variable in UNIX?

Question

``` #!/bin/bash if [ ! $1 ] then echo "no param" else set FAV_COLOR=$1 echo "My fav color is ${FAV_COLOR}" fi ``` This is not working how I expected: ``` >favcol.sh blue My fav color is FAV_COLOR=blue ``` Any thoughts?

Accepted Answer

Remove `set`.

```
FAV_COLOR=$1
echo "My fav color is ${FAV_COLOR}"
```

Or if you want to set it so that it is available to subsequent programs run in the shell:

```
export FAV_COLOR=$1
echo "My fav color is ${FAV_COLOR}"
```

The `export` keyword is described fairly well here.
