Bash command substitution not working as expected

The reason that it doesn't work is because stty is executed within a pipe. Therefore it doesn't "see" the underlying terminal. In your script you could store the terminal width in a variable like

size=`stty size | cut -d" " -f2`

and then use that next:

tail $FILE | cut -c -$size
cut -f5 $1
date |cut -d " " -f 4
date| cut -d " " -f 4

In bash, how do I pass the while loops input to the cut command?

Use echo:

login=$(echo "$line" | cut -d : -f 1)


Print selected parts of lines from each FILE to standard output.

Mandatory arguments to long options are mandatory for short options too.
, --bytes=LIST

select only these bytes

-c, --characters=LIST

select only these characters

-d, --delimiter=DELIM

use DELIM instead of TAB for field delimiter

-f, --fields=LIST

select only these fields; also print any line that contains no delimiter character, unless the -s option is specified




complement the set of selected bytes, characters or fields

-s, --only-delimited

do not print lines not containing delimiters


use STRING as the output delimiter the default is to use the input delimiter


display this help and exit


output version information and exit

Use one, and only one of -b, -c or -f. Each LIST is made up of one range, or many ranges separated by commas. Selected input is written in the same order that it is read, and is written exactly once. Each range is one of:


N’th byte, character or field, counted from 1


from N’th byte, character or field, to end of line


from N’th to M’th (included) byte, character or field


from first to M’th (included) byte, character or field

With no FILE, or when FILE is -, read standard input.
