I am doing a program that will calculate the 199th fibonacci number using pipelines and multiple processes for each calculation. I have figured everything out except why none of the processes before the last one never execute the findfib() function;

My problem is more a question of how to do it more elegantly than how to do it at all. The problem:
I have a pipeline which has to write to the screen AND to a logfile:
proc1 | tee -a <logfile>
What makes things difficult is i also need the return code of proc1. But
proc1 | tee -a... (6 Replies)

Hi all,
I have a tar file and inside that tar file is a folder with additional tar.gz files. What I want to do is look inside the first tar file and then find the second tar file I'm looking for, look inside that tar.gz file to find a certain directory. I'm encountering issues by trying to... (1 Reply)
I would like to confirm my file.tar is been tar-ed correctly before I remove them. But I have very limited disc space to untar it.
Can I just do the listing instead of actual extract it? Can I say confirm folder integrity if the listing is sucessful without problem?
tar tvf file1.tar

Coming from this thread, just wondering if there is an option to check if the Tar of the files/directory will be without any file-errors without actually making the tar.
Scenario:
Let's say you have a directory of 20GB, but you don't have the space to make Tar file at the moment, and you want... (14 Replies)

APPLESINGLE(1) BSD General Commands Manual APPLESINGLE(1)NAME
applesingle, binhex, macbinary -- encode and decode files
SYNOPSIS
<tool> probe file ...
<tool> [decode] [-c] [-fv] [-C dir] [-o outfile] [file ...]
<tool> -h | -V
applesingle encode [-cfv] [-s suf] [-C dir] [-o outfile] file ...
binhex encode [-R] [-cfv] [-s suf] [-C dir] [-o outfile] file ...
macbinary encode [-t 1-3] [-cfv] [-s suf] [-C dir] [-o outfile] file ...
DESCRIPTION
applesingle, binhex, macbinary are implemented as a single tool with multiple names. All invocations support the three verbs encode, decode,
and probe.
If multiple files are passed to probe, the exit status will be non-zero only if all files contain data in the specified encoding.
OPTIONS -f, --force
perform the operation even if the output file already exists
-h, --help
display version and usage, then quit
-v, --verbose
be verbose
-V, --version
display version, then quit
-c, --pipe, --from-stdin, --to-stdout
For decode, read encoded data from the standand input. For encode, write encoded data to the standard output. Currently, "plain"
data must be written to and from specified filenames (see also mount_fdesc(8)).
-C, --directory dir
create output files in dir
-o, --rename name
Use name for output, overriding any stored or default name. For encode, the appropriate suffix will be added to name. -o implies
only one file to be encoded or decoded.
-s, --suffix .suf
override the default suffix for the given encoding
-R, --no-runlength-encoding
don't use BinHex runlength compression when encoding
-t, --type 1-3
Specify MacBinary encoding type. Type 1 is undesirable because it has neither a checksum nor a signature and is thus difficult to
recognize.
DIAGNOSTICS
In general, the tool returns a non-zero exit status if it fails.
