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
source
In bash, how do I pass the while loops input to the cut command?
Use echo:
login=$(echo "$line" | cut -d : -f 1)
description
Print selected
parts of lines from each FILE to standard output.
Mandatory
arguments to long options are mandatory for short options
too.
-b, --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
complement the set of selected
bytes, characters or fields
-s,
--only-delimited
do not print lines not
containing delimiters
--output-delimiter=STRING
use STRING as the output
delimiter the default is to use the input delimiter
--help
display this help and exit
--version
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
N’th byte, character or field, counted from 1
N-
from N’th byte, character or field, to end of
line
N-M
from N’th to M’th (included) byte, character
or field
-M
from first to M’th (included) byte, character or
field
With no FILE,
or when FILE is -, read standard input.
