Whats wrong with my function?? <newbie>
First of all im using Bash, on a Debian-based machine. I tried to write a function that if the ls program found listed more than 25 lines I would automaticly use "ls | less". Its on another computer but if I recall it looked something like this...
Note: some code may look strange because im on this stupid spanish keyboard where nothing does as it says...
Quote:
master_ls() {
if [ "$(ls -F)" -gt "25" ]
then
ls - F | less
else
ls - F
}
I tried assigning it to "ls" with the effect of (i think) infinite recursion.
System crashed...
Also tried assigning it to "lss" with the SAME problem (i think).
System crashed...
In despair i just tried to create an alias like:
alias lss="ls -F | less"
which only worked in the current directory..
also tried: lss="ls -F $@ | less" and lss="ls -F ${@:-$(pwd)}"
Have no idea what to do...
Regards
Richard

update-fonts-alias
update-fonts-alias(8) System Manager's Manual update-fonts-alias(8)
NAME
update-fonts-alias - compile fonts.alias files
SYNOPSIS
update-fonts-alias [OPTION] directory ...
DESCRIPTION
update-fonts-alias assembles a fonts.alias file in an X font directory using one or more alias files found in a subdirectory of
/etc/X11/fonts/. It is typically invoked only from the post-installation and post-removal scripts of a package containing X Window System
fonts that provide aliases for their XLFD names, but may be invoked at any time to reconstruct fonts.alias files. For each directory,
which is simply the last component of its path (such as '75dpi' or 'misc'), update-fonts-alias will assemble either
/usr/lib/X11/fonts/directory/fonts.alias or /usr/share/fonts/X11/directory/fonts.alias from the files found in /etc/X11/fonts/direc-
tory/package.alias.
This enables multiple packages to provide aliases for fonts in the same directory. No font package actually provides the fonts.alias file
in the X font directory itself, so there is no danger of overwriting one package's aliases with those of another.
For instance, the two packages 'xfonts-base' and 'xfonts-base-transcoded' may both install fonts into the directory
/usr/lib/X11/fonts/misc. They each place their fonts.alias files in /etc/X11/fonts/misc/xfonts-base.alias and
/etc/X11/fonts/misc/xfonts-base-transcoded.alias (respectively). update-fonts-alias concatenates these two files (as well as any others
that match /etc/X11/fonts/misc/*.alias) into /usr/lib/X11/fonts/misc/fonts.alias.
The format of fonts.alias files is described in the mkfontdir(1x) manual page.
An example of how to use update-fonts-alias in package maintainer scripts is provided in the Debian Policy Manual.
OPTIONS
-h, --help displays a brief usage message and exits.
OPERANDS
update-fonts-alias takes one or more X font directory names to operate on as operands. Only the final path component of the directory name
should be specified; e.g.,
update-fonts-alias 75dpi
is correct, while 'update-fonts-alias /usr/X11R6/lib/X11/fonts/75dpi' and 'update-fonts-alias /usr/lib/X11/fonts/75dpi' are not.
ENVIRONMENT
COLUMNS
indicates the width of the terminal device in character cells. This value is used for formatting diagnostic messages. If not set,
the terminal is queried using stty(1) to determine its width. If that fails, a value of '80' is assumed.
DIAGNOSTICS
Errors
usage error: one or more font directories must be provided
update-fonts-alias was invoked without operands. Supply one or more X font directory names to operate on.
usage error: unrecognized option
update-fonts-alias was invoked with an unrecognized option argument. Use only the options documented in "OPTIONS", above.
fatal error: path to X font directory must be used
A directory name was supplied that was not an X font directory name. Supply X font directory names only.
Warnings
warning: absolute path directory was provided
Usage of absolute paths is deprecated. Use only the final component of the X font directory name for directory.
warning: directory does not exist or is not a directory
The supplied directory was invalid. update-fonts-alias skipped it.
EXIT STATUS
0 update-fonts-alias ran successfully.
1 update-fonts-alias experienced a fatal error; see the section on diagnostic messages above.
2 update-fonts-alias was invoked with invalid arguments.
BUGS
See the Debian Bug Tracking System <http://bugs.debian.org/xfonts-utils>. If you wish to report a bug in update-fonts-alias, please see
/usr/share/doc/debian/bug-reporting.txt or the reportbug(1) command.
