I have a tab delimited table with more than 126 columns. One of the columns however contains more than 90 characters and this makes the table really difficult to read. I know I can use awk and printf to format the width but then I'll need to write, $1, $2, $3, ...:

Hi all,
I have a shell script which uses "mailx -H" to get the subject of a email in a Linux system.
However, the subject is truncated, and I think it has something to do with the terminal width because it only returns the first 80 characters of each line.
I have tried "stty columns"... (7 Replies)

htop(1) Utils htop(1)
NAME
htop - interactive process viewer
SYNTAX
htop
DESCRIPTION
This program is a free (GPL) ncurses-based process viewer.
It is similar to top, but allows to scroll the list vertically and horizontally to see all processes and their full command lines.
Tasks related to processes (killing, renicing) can be done without entering their PIDs.
COMMAND-LINE OPTIONS
The following flags are supported:
-d DELAY
Delay between updates, in tenths of seconds
-u USERNAME
Show only processes of a given user
--sort-key COLUMN
Sort by this column (use --sort-key help for a column list)
INTERACTIVE COMMANDS
The following commands are supported:
Arrows, PgUP, PgDn, Home, End
Scroll process list.
Space
"Tag": mark a process. Commands that can operate on multiple processes, like "kill", will then apply over the list of tagged pro-
cesses, instead of the currently highlighted one.
U "Untag" all processes (remove all tags added with the Space key).
s Trace process system calls: if strace(1) is installed, pressing this key will attach it to the currently selected process, presenting
a live update of system calls issued by the process.
l Display open files for a process: if lsof(1) is installed, pressing this key will display the list of file descriptors opened by the
process.
F1, h
Help screen
F2, S
Setup screen. There you can configure meters displayed on the top side of the screen, as well as set various display options, choose
among color schemes and select the layout of the displayed columns.
F3, /
Incremental process search: type in part of a process command line and the selection highlight will be moved to it. While in search
mode, pressing this key will cycle through matching occurrences.
F4, I
Invert sort order: if sort order is increasing, switch to decreasing, and vice-versa.
F5, t
Tree view: organize processes by parenthood, and layout the relations between them as a tree. Toggling the key will switch between
tree and your previously selected sort view. Selecting a sort view will exit tree view.
F6, >
Select field for sorting. The sort field is indicated by a highlight in the header.
F7, ], -
Increase selected process priority (subtract from 'nice' value). This can be done by the superuser only.
F8, [, +
Decrease selected process priority (add to 'nice' value)
F9, k
"Kill" process: sends a signal which is selected in a menu, to one or a group of processes. If processes were tagged, sends the signal
to all tagged processes. If none is tagged, sends to the currently selected process.
F10, q
Quit
+, - When in tree view mode, expand or collapse subtree. When a subtree is collapsed a "+" sign shows to the left of the process name.
a (on multiprocessor machines)
Set CPU affinity: mark which CPUs a process is allowed to use.
u Show only processes owned by a specified user.
M Sort by memory usage (top compatibility key).
P Sort by processor usage (top compatibility key).
T Sort by time (top compatibility key).
F "Follow" process: if the sort order causes the currently selected process to move in the list, make the selection bar follow it. This
is useful for monitoring a process: this way, you can keep a process always visible on screen. When a movement key is used, "follow"
loses effect.
K Hide kernel threads: prevent the threads belonging the kernel to be displayed in the process list. (This is a toggle key.)
H Hide user threads: on systems that represent them differently than ordinary processes (such as recent NPTL-based systems), this can
hide threads from userspace processes in the process list. (This is a toggle key.)
Ctrl-L
Refresh: redraw screen and recalculate values.
Numbers
PID search: type in process ID and the selection highlight will be moved to it.
