I want to delete the first line of all files in a folder if the file starts with uuid, and so I have a working command sedthat looks like this:
$ sed -i '' '/^uuid/d' *
which works fine and removes all lines starting with uuid.
Now I want to improve the script by deleting only the first line if it starts with uuid, as some files have several uuid: s, and only one in the first line should be deleted. So now I have improved the command to look like this:
$ sed -i '' '1{/^uuid/d;}' *
Now this command also works, but only in the first file in the folder and even if I run a simple (just delete the first line) version, for example:
$ sed -i '' '1d' *
it still affects only the first file.
Why is this?
Mac ( BSD- sed, ), gnu-sed Brew, $ brew install gnu-sed --with-default-names, .
sed - 25 ,
sed - 20 / googled sed

$ sed -s '1d' ./*
sed: illegal option -- s
man sed, -s & --seperate, - .
2: , ... find . -iname '*.yml' -exec sed -i '' -e '1{/uuid/d;}' {} \; , sed: can't read : No such file or directory
