Removing columns of characters from a line

In a file with a similar content shown below, one can remove certain
columns based on the delimiters.

aaa:123:sometext1:name1:zz
bbbbbbb:44457:sometext2:name2:yy2
ccccc:783456:sometext3:name3:xx3

If, for example, one wants to remove the part sometext# in each line,
use the following command

cut -d: -f1,2,4,5 filename

: is the delimiting character.
filename is the name of the file that contains the text (duh!!)


If the delimiter is space, such as the following

bb1 457 sometext2 name2 yy2

use the following command:

cut -d' ' -f1,2,4,5 filename
