The authors of Gnu ls changed 'ls' defaults because "they can".
Old ls -C:
331 379 913 filesystems mounts registry32 swaps version
332 500 cpuinfo loadavg net registry64 sys
335 731 cygdrive meminfo partitions self sysvipc
new ls -C:
law.Bliss> /bin/ls /proc|column (tabs mismatch)
331 731 devices net stat
332 732 filesystems partitions swaps
335 952 loadavg registry sys
370 953 meminfo registry32 sysvipc
379 cpuinfo misc registry64 uptime
500 cygdrive mounts self version
with column+expand -8:
s> /bin/ls /proc|column|expand -8
1021 379 devices net stat
1022 500 filesystems partitions swaps
331 731 loadavg registry sys
332 732 meminfo registry32 sysvipc
335 cpuinfo misc registry64 uptime
370 cygdrive mounts self version
several other tools no longer have settings to expand tabs to user-values
requiring the use of expand.
Formats of numeric output were also changed, requiring usage of 'numfmt'
This was all done to benefit script consistency at the expense of
users usability. It is expected that users can adapt to the computers.
by default, 'ls' will produce different output when it goes to the
screen vs. when
it goes to a pipe. When 'ls' goes to a pipe it is required to only use
To get the behavior you want, try piping through 'column' first (see
'man (1) column).
They made many changes in core-utils to make automated shell scripts more
consistent at the expense of user-usability where they now suggest using
pipes into other utilities to get previous output
Try using ls|column. Of course ls also used to expand tabs to every 8
and it no longer does that. So you must use another util 'tabs' to set
tabs to every
8th column (ls's standard tab setting)
