According to command >& file redirects the standard output and error messages to the file.
An additional! normally has no effect, unless there was a previous set noclobber (that is inhibited then).
I created this bash script. However when I tried to do it using csh, 2>&1 | tee $fout.log did not work.
#!/bin/bash
data=$1
inmod=$2
nxz=$3
data=` echo $data | awk 'BEGIN { FS=".dat" } { print $1 }' `
inmod=` echo $inmod | awk 'BEGIN { FS=".vmod" } { print $1 }' `

Q1. I understand that /usr/local/bin means I can install/uninstall stuff in here and have any chance of messing up my original system files or effecting any other users. I created this directory myself.

I'm having a strange problem with basic >& output redirection to a simple log file in csh.

Nothing is output to the... (5 Replies)

nice(1) User Commands nice(1)NAME
nice - invoke a command with an altered scheduling priority
SYNOPSIS
/usr/bin/nice [-increment | -n increment] command
[argument]...
/usr/xpg4/bin/nice [-increment | -n increment] command
[argument]...
csh Builtin
nice [-increment | +increment] [command]
DESCRIPTION
The nice utility invokes command, requesting that it be run with a different system scheduling priority. The priocntl(1) command is a more
general interface to scheduler functions.
The invoking process (generally the user's shell) must be in a scheduling class that supports nice.
If the C shell (see csh(1)) is used, the full path of the command must be specified. Otherwise, the csh built-in version of nice will be
invoked. See csh Builtin below.
/usr/bin/nice
If nice executes commands with arguments, it uses the default shell /usr/bin/sh (see sh(1)).
/usr/xpg4/bin/nice
If nice executes commands with arguments, it uses /usr/xpg4/bin/sh (see ksh(1)).
csh Builtin
nice is also a csh built-in command with behavior different from the utility versions. See csh(1) for description.
OPTIONS
The following options are supported:
-increment | -n increment increment is a positive or negative decimal integer that has the same effect on the execution of the utility
as if the utility had called the nice() function with the numeric value of the increment option-argument. See
nice(2). nice() errors, other than EINVAL, are ignored. If not specified, an increment of 10 is assumed.
The super-user may run commands with priority higher than normal by using a negative increment such as -10. A
negative increment assigned by an unprivileged user is ignored.
OPERANDS
The following operands are supported:
command The name of a command that is to be invoked. If command names any of the special built-in utilities (see shell_builtins(1)),
the results are undefined.
argument Any string to be supplied as an argument when invoking command.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of nice: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, PATH, and NLSPATH.
EXIT STATUS
If command is invoked, the exit status of nice will be the exit status of command. Otherwise, nice will exit with one of the following val-
ues:
1-125 An error occurred.
126 command was found but could not be invoked.
127 command could not be found.
