I want to execute a command something like:
find / -name "jni.h"
and I want to direct the output of that command to some type of
filter that will leave out all the lines reporting inaccessible
directories (permission unavailable). Is this a pipe or a redirect?
For example, output like... (1 Reply)
Hello,
There is pipe chain and I want concacenate piped data with some variable:
balh blah| ... $var1
What command I should use instead ... to concatenate piped output with $var1. I think I coud solve this using temp var - but could it be done in one line like sample above ?
thanks... (4 Replies)
Currently, i am trying to create a simple robust script that is intended to move the contents of a given source directory to a target directory. Optionally, the script should allow to either move the whole source dir content, or dotfiles only, or visible files only. I am aware the target directory... (0 Replies)
Is there a way to keep the output of a script displayed on the terminal when it's run by itself, but suspend part of that output and only have a specific part delivered when it's piped to another script or program? I'm thinking something like the following pseudocode:
#!/bin/bash

Hi All,
When starting an SSH tunnel, piped output 'hangs' (on AIX) :
ssh -Nf -Llocalhost:22000:server:22 proxy | cat -vet -
... hangs ...
Does anybody know how to prevent this?
Of course, in my script I don't use the tunnel as I do in the example above. In my script the call to ssh is... (7 Replies)

Hello,
I'm pretty stumped, and I don't know why I am not able to redirect the output to the 'graphme' file with the command below in Fedora 18.

to run most other scripts through a pipe, something similar to the following is usually enough:
cat script.sh | sh
cat perl.pl | perl -- "<arguments"
However, for javascript command line scripts, i cant seem to get this to work. Any ideas?
cat hull.js

b64encode
UUENCODE(1) BSD General Commands Manual UUENCODE(1)NAME
uuencode, uudecode, b64encode, b64decode -- encode/decode a binary file
SYNOPSIS
uuencode [-m] [-o output_file] [file] name
uudecode [-cimprs] [file ...]
uudecode [-i] -o output_file
b64encode [-o output_file] [file] name
b64decode [-cimprs] [file ...]
b64decode [-i] -o output_file [file]
DESCRIPTION
The uuencode and uudecode utilities are used to transmit binary files over transmission mediums that do not support other than simple ASCII
data. The b64encode utility is synonymous with uuencode with the -m flag specified. The b64decode utility is synonymous with uudecode with
the -m flag specified.
The uuencode utility reads file (or by default the standard input) and writes an encoded version to the standard output, or output_file if
one has been specified. The encoding uses only printing ASCII characters and includes the mode of the file and the operand name for use by
uudecode.
The uudecode utility transforms uuencoded files (or by default, the standard input) into the original form. The resulting file is named
either name or (depending on options passed to uudecode) output_file and will have the mode of the original file except that setuid and exe-
cute bits are not retained. The uudecode utility ignores any leading and trailing lines.
The following options are available for uuencode:
-m Use the Base64 method of encoding, rather than the traditional uuencode algorithm.
-o output_file
Output to output_file instead of standard output.
The following options are available for uudecode:
-c Decode more than one uuencoded file from file if possible.
-i Do not overwrite files.
-m When used with the -r flag, decode Base64 input instead of traditional uuencode input. Without -r it has no effect.
-o output_file
Output to output_file instead of any pathname contained in the input data.
-p Decode file and write output to standard output.
-r Decode raw (or broken) input, which is missing the initial and possibly the final framing lines. The input is assumed to be in the
traditional uuencode encoding, but if the -m flag is used, or if the utility is invoked as b64decode, then the input is assumed to be
in Base64 format.
-s Do not strip output pathname to base filename. By default uudecode deletes any prefix ending with the last slash '/' for security
reasons.
EXAMPLES
The following example packages up a source tree, compresses it, uuencodes it and mails it to a user on another system. When uudecode is run
on the target system, the file ``src_tree.tar.Z'' will be created which may then be uncompressed and extracted into the original tree.
tar cf - src_tree | compress |
uuencode src_tree.tar.Z | mail user@example.com
The following example unpacks all uuencoded files from your mailbox into your current working directory.
uudecode -c < $MAIL
The following example extracts a compressed tar archive from your mailbox
uudecode -o /dev/stdout < $MAIL | zcat | tar xfv -

The uudecode and uuencode utilities appeared in 4.0BSD.
BUGS
Files encoded using the traditional algorithm are expanded by 35% (3 bytes become 4 plus control information).
