Wrote the following simple .sh script which should save output.txt to the working directory:
valuesfile="values.*"
for f in ./
do
if [[ $f = $valuesfile ]]
then
yq d $f 'resources.' >./output.txt
fi
done
When I execute the script, no file is created. all folders have rwx permissions including the script itself.
Your condition can never be true, and therefore, yq is never executed.
The loop body is executed exactly once, with f set to the string ./, and valuesfile is set to the string values.*. These strings are obviously not equal.
=~ operator, not by =. For finding files where the name starts with values, a regexp is overkill. Wildcard pattern match is sufficient. You could much a filename stored in variable filename simply by [[ $filename == values* ]]. Of course even this would not fix your problem, because of the non-sense value stored in your variable f....Just read this piece of code:
valuesfile="values.*"
...
if [[ $f = $valuesfile ]]
I don't think that any file can be called values.*, I'm expecting something like values.1 or values.txt, but a filename containing an asterisk look weird to me.
Edit after comment
I propose the following:
valuesfile="values.*"
for f in ./$valuesfile
do
yq d $f 'resources.' >./output.txt
done
for f in ./$valuefile should do the trick, isn't it? No need for the if-clause.Your glob is never expanded: unquoted parameter expansions inside [[ ... ]] do not undergo pathname expansions. Your loop is also incorrect: for f in ./ iterates exactly once, setting f to the string ./, rather than iteration over the files in the current directly. And finally, if there are more than one matching file, you'll repeatedly overwrite the previous contents of output.txt; use >> instead.
You could try
valuesfile="values.*"
for f in ./$valuesfile
do
yq d "$f" 'resources.' >> ./output.txt
done
though this will cause problems if any of your files have whitespace, as the expansion of $valuesfile undergoes word-splitting as well as pathname expansion.
Use an array instead:
valuesfile=( values.* )
for f in "${valuesfile[@]}"
do
yq d "$f" 'resources.' >> output.txt
done
Or, just dispense with the extra variable and put the pattern in the loop directly:
for f in values.*
do
yq d "$f" 'resources.' >> output.txt
done
yqbut thedlooks strange. Usually one would expect an option to be proceeded by at least 1-ifwill never execute.lshere.
