Not with a single input source piped into something. Note that you open and read test.txt twice in your above construct. You could do (but this is far from being smart nor efficient)
Code:
cat <(docker image ls | head -n1) <(docker image ls | tail -n+2 | sort -Vrk5 )
You might feel inspired to use tee to split the input into different branches of execution, but it'd be difficult to predict the resultant order of lines. This clumsy approach seems to do it on my system
Code:
docker image ls | tee >(head -n1) >(tail -n+2 | sort -rk5) > /dev/null
, but, again, this is far from using common sense.
Dear Experts
I am trying to find if it is possible to combine unix commands in awk program. For example if it is possible embed rm or ls or any unix command inside the awk program and while it is reading the file besides printing be able to do some unix commands. I am thinking may be just print... (2 Replies)
Hello,
I am trying, utilizing the few commands I know, to extract all records within my file that were generated in November of 2007. Each record within the file has a "date" field giving the month, day, and year (9-8-88). How do I extract those records to their own file?
Once I extract... (4 Replies)
How can I direct awk output to go nowhere? I can write the data to a file easy enough or print it on the screen. But for this particular command I don't actually want the data and I don't want to create a file. I just want the data discarded.
Thanks in advance (3 Replies)
Hello everyone, I've suddenly gotten very interested in sed and awk (and enjoying it quite a bit too) because of a large conversion project that we're working on. I'm currently stuck with a very inefficient process for processing text blocks. I'm sure someone here should be able to easily point out... (2 Replies)
I've run into a problem getting exactly what I want out of awk - some folks may recognize this as an output from Amazon's ec2-describe-instances:

Hi there is there a way to assing variable a value that is output of a program in awk script. For e.g., I did

but it does not work.
Any advice???

What is the correct syntax to pipe or run three awk commands? Basically, using the output of the first awk as input in the second. Then using the output of the second awk in the third. Thank you :).

In the awk below the first sample MEV45 gets extracted from the html, but the subsequent MEV46 and MEV47 do not as they are not part of parse. I can not seem to add them to the code. Thank you very much @RudiC your awk is very nice :).

mcx convert(1) USER COMMANDS mcx convert(1)
NAME
mcx convert - convert between mcx storage types
SYNOPSIS
mcx convert <matrix-file-in> <matrix-file-out>
mcx convert [--write-binary] --cone-to-stack <cat-file-in> <cat-file-out>
mcx convert [--write-binary] --stack-to-cone <cat-file-in> <cat-file-out>
mcxconvert is not in actual fact a program. This manual page documents the behaviour and options of the mcx program when invoked in mode
convert. The options -h, --apropos, --version, -set, --nop, -progress <num> are accessible in all mcx modes. They are described in the mcx
manual page.
mcx convert [--cone-to-stack (transform cone file to stack file)] [--stack-to-cone (transform stack file to cone file)] [--write-binary
(output native binary format)] [--cat (read and write cat format)] [-cat-max <num> (limit the stack conversion to <num> matrices)]
In the two-argument invocation without additional arguments, mcx convert converts from the format found in the first file to the other for-
mat, i.e. from native interchange to native binary format or the other way around. When querying with the -q option, mcx{convert} will out-
put a one-line synopsis describing the matrix in the argument. The --cone-to-stack and --stack-to-cone options convert between the two types
of concatenated output provided by mclcm.
DESCRIPTION
The mcl libraries make extensive use of matrices. Matrices are used to encode graphs, matrices and clusterings. They can be stored either
in interchange or in binary format. The latter is somewhat more efficient in storage and much faster in both reading and writing, but the
default is interchange format.
The mcl input routines recognize the type of storage they are dealing with. If you want to convert a matrix to the other storage type, sim-
ply specify the file name of the matrix you want to convert. mcx convert will recognize its type, and write the other type to the file
specified as the second argument.
OPTIONS
--cone-to-stack (transform cone file to stack file)
This option requires two trailing options, the names of respectively the source cone file and the target stack file.
--stack-to-cone (transform stack file to cone file)
This option requires two trailing options, the names of respectively the source stack file and the target cone file.
--cat (read and write cat format)
-cat-max <num> (limit the stack conversion to <num> matrices)
--write-binary (output native binary format)
This option is only useful with either of the options --cone-to-stack, --stack-to-cone, or --cat.
