Removing columns in text files (colrm command)

Edit online

Use the colrm command to remove specified columns from a file. Input is taken from standard input. Output is sent to standard output.

If the command is called with one parameter, the columns of each line from the specified column to the last column are removed. If the command is called with two parameters, the columns from the first specified column to the second specified column are removed.

Note: Column numbering starts with column 1.

See the following examples:

To remove columns from the text.fil file, type the following:
```
colrm 6 < text.fil
```
If text.fil contains:
```
123456789
```
then the colrm command displays:
```
12345
```

See the colrm command in the Commands Reference, Volume 1 for the complete syntax.
