Development pattern for contributors
------------------------------------
1. [Create a personal fork](https://help.github.com/articles/fork-a-repo/)
of the [main Kaldi repository](https://github.com/kaldi-asr/kaldi) in GitHub.
2. Make your changes in a named branch different from `master`, e.g. you create
a branch `my-awesome-feature`.
3. [Generate a pull request](https://help.github.com/articles/creating-a-pull-request/)
through the Web interface of GitHub.
4. As a general rule, please follow [Google C++ Style Guide](https://google.github.io/styleguide/cppguide.html).
There are a [few exceptions in Kaldi](http://kaldi-asr.org/doc/style.html).
You can use the [Google's cpplint.py](https://raw.githubusercontent.com/google/styleguide/gh-pages/cpplint/cpplint.py)
to verify that your code is free of basic mistakes.
Platform specific notes
-----------------------
### PowerPC 64bits little-endian (ppc64le)
- Kaldi is expected to work out of the box in RHEL >= 7 and Ubuntu >= 16.04 with
OpenBLAS, ATLAS, or CUDA.
- CUDA drivers for ppc64le can be found at [https://developer.nvidia.com/cuda-downloads](https://developer.nvidia.com/cuda-downloads).
- An [IBM Redbook](https://www.redbooks.ibm.com/abstracts/redp5169.html) is
available as a guide to install and configure CUDA.
### Android
- Kaldi supports cross compiling for Android using Android NDK, clang++ and
OpenBLAS.
- See [this blog post](http://jcsilva.github.io/2017/03/18/compile-kaldi-android/)
for details.
### Web Assembly
- Kaldi supports cross compiling for Web Assembly for in-browser execution
using [emscripten](https://emscripten.org/) and CLAPACK.
- See [this post](https://gitlab.inria.fr/kaldi.web/kaldi-wasm/-/wikis/build_details.md)
for a step-by-step description of the build process.Community Discussions

QUESTION
Is this sed command valid?
Asked 2022-Jan-15 at 08:48I have 2 lines of sed that I have trouble understanding
I understand that the syntax of sed is :
sed OPTIONS [SCRIPT] [INPUTFILE]
but in this command below there is no input file I am just curious what this is doing, any help is very much appreciated
1.
$(echo $d | sed 's/.*\///g')#
cat /kaldi/README | sed "s/akiplaner/${n}/g" > extracted/$nf/etc/README #
*note : below is the whole code
for d in /dir1/dataset/audios/*; do
echo $d
n=$(echo $d | sed 's/.*\///g') #
nf=${n}
echo $n $a $nf
mkdir -p extracted/$nf/wav
mkdir -p extracted/$nf/etc
rm -f extracted/$nf/etc/prompts-original
rm -f extracted/$nf/etc/PROMPTS
cat /kaldi/README | sed "s/akiplaner/${n}/g" >extracted/$nf/etc/README #
for f in $d/*.wav; do
n2=$(echo $f | sed 's/.*\///g')
n3=$(echo $n2 | sed 's/\.wav//g') # removing .wav from $n2 string
echo $n2
echo $n3
cp $f extracted/$nf/wav/$n2
#sox --vol 0.01 $f -t wav extracted/$nf/wav/$n2;
normalize-audio -a 0.3 extracted/$nf/wav/$n2
cp $d/$n3.txt temp.txt
echo "$n3 $(cat temp.txt)" >>extracted/$nf/etc/prompts-original
echo "${nf}/mfc/${n3} $(cat temp.txt)" >>extracted/$nf/etc/PROMPTS
done
a=$(($a + 1))
done
ANSWER

The answer is at your fingertips.
$ LC_ALL=C sed --help
...
... if no input files are
specified, then the standard input is read.
Note: | shell operator connects one command standard output to another command's standard input. There are surely endless resources on the internet for basic introduction to shell streams and input output operations - it might be a good occasion to research some of them, like https://mywiki.wooledge.org/BashGuide/InputAndOutput .
sed OPTIONS [SCRIPT] [INPUTFILE]
It's:
$ LC_ALL=C sed --help
Usage: sed [OPTION]... {script-only-if-no-other-script} [input-file]...
The stuff in [...] is optional. ... represents stuff it can be repeated.
There are man problems with the script - it will break on filenames with spaces or newlines in the name or on filenames with * in the name... Remember to check your scripts with shellcheck - it will catch such mistakes.
's/.*///g' am I correct in saying this pattern is removing any file or folder whose name starts with
From a line of text it removes everything .* before a / slash. You can learn regex with fun with https://regexcrossword.com/ and sed here https://www.grymoire.com/Unix/Sed.html .
It's an odd way of writing basename "$n" and the next line is just basename "$n" .wav.
