by doing the following command in the folder
ls -d */ | cut -f1 -d'/'
I get entries like:
env1
env2
env3
env4
how I can use cat/grep or yq/jq or any other alternative command(s) instead of the above command?

What use are you later making of these entries? Iterating over them in a shell script? Or just printing to stdout?– Charles DuffyCommented Sep 30, 2020 at 20:32

What you want to achieve? Just list the directories in the current directory?– kofemannCommented Sep 30, 2020 at 20:33

@kofemann I'm using this command as a script in my groovy code using in helm file to print the list of environments in the output, using this command it print a list of env sequentially, but I need to print them in parallel– sasanCommented Sep 30, 2020 at 20:37

You mean print them on the same line?– Charles DuffyCommented Sep 30, 2020 at 20:53

for dir in */; do
echo "${dir%/}"
done
There are several options. You can use the tree command with the options:
# d: list only directories
# i: no print of indention line
# L: max display depth of the directory tree
tree -di -L 1 "$(pwd)"
Or you can also use the grep command to get the directories and the command awk:
# F: input field separator
# $9: print the ninth column of the output
ls -l | grep "^d" | awk -F" " '{print $9}'
Or you can use the sed command to remove the slash:
# structure: s|regexp|replacement|flags
# g: apply the replacement to all matches to the regexp, not just the first
ls -d */ | sed 's|[/]||g'
I found this solutions in this post.
