Execute multiple commands against a specific file if found in a directory recusively

I have 2 directories paul & matt with some subfolders within each which potentially contains (or will contain) a kustomization.yaml file. What I am trying to do is to run multiple commands in the path where a kustomization.yaml is found in paul/* and matt/*. So if I was to do this manually:

cd paul
somecommand1 kustomization.yaml
somecommand2 kustomization.yaml
cd paul/test
somecommand1 kustomization.yaml
somecommand2 kustomization.yaml
cd paul/test/test1
somecommand1 kustomization.yaml
somecommand2 kustomization.yaml
---
cd matt
somecommand1 kustomization.yaml
somecommand2 kustomization.yaml
cd matt/test
somecommand1 kustomization.yaml
somecommand2 kustomization.yaml
cd matt/test/test1
somecommand1 kustomization.yaml
somecommand2 kustomization.yaml

I am still learning bash but I know that a Bash script I can call on my GitLab pipeline with some steps that will do something like a loop to find any kustomization.yaml in those 2 directories recursively, then run x, y, and z against any found kustomization.yaml file will do the job.

Solution

You could use find command with multiple use of -exec option like that:

find matt paul -name "kustomization.yaml" \
  -exec echo -n "Work on '{}' file in " \; -exec pwd \; \
  -exec somecommand1 {} \; \
  -exec somecommand2 {} \;

Alternative

Use -execdir option to execute commands in the directory where file found.

find matt paul -name "kustomization.yaml" \
  -execdir echo -n "Work on '{}' file in: " \; -execdir pwd \; \
  -execdir somecommand1 {} \; \
  -execdir somecommand2 {} \;

Alternative 2

Use a subscript: /some/path/my_commands.sh

#! /usr/bin/env bash

# cd "${1%/*}" # Necessary if you use `-exec` option instead of `-execdir`
echo "Work on '$1' in '$(pwd)' directory"
somecommand1 "$1"
somecommand1 "$1"

chmod +x /some/path/my_commands.sh

And use only one -execdir option:

find matt paul -name "kustomization.yaml" \
  -execdir /some/path/my_commands.sh {} \;

This alternative is very useful if you want to make treatments with return codes from somecommand* executions:

Subscript: /some/path/my_commands.sh

#! /usr/bin/env bash

# cd "${1%/*}" # Necessary if you use `-exec` option instead of `-execdir`
# It may be important to check the return code of `cd` command before continue
# if [[ $? -ne 0 ]]; then
#   echo "ERR: ${0##*/}: Cannot change directory to '${1%/*}'" >&2
#   exit 1
# fi

echo "Work on '$1' file in '$(pwd)' directory"

if somecommand1 "$1"; then
  ...
else
  ...
fi
...
if somecommand2 "$1"; then
  ...
else
  ...
fi
