truncate output in BASH

Question

How do I truncate output in BASH? For example, if I "du file.name" how do I just get the numeric value and nothing more? later addition: all solutions work perfectly. I chose to accept the most enlightning "cut" answer because I prefer the simplest approach in bash files others are supposed to be able to read.

Accepted Answer

If you know what the delimiters are then cut is your friend

```
du | cut -f1
```

Cut defaults to tab delimiters so in this case you are selecting the first field.

You can change delimiters: cut -d ' ' would use a space as a delimiter. (from Tomalak)

You can also select individual character positions or ranges:

```
ls | cut -c1-2
```
