permission denied when sed in place edit in mingw

问题

I'm using mingw.

  $ sed -i "s/a/b/" test.txt
  sed: preserving permissions for `./sed003480': Permission denied

I can touch/rm files in current dir.

回答1:

It's caused by Windows security settings.

Open the folder's Properties settings from the context menu. In the Security tab, click Edit, press Add... in the pop-up window and add your user to the list, check Full Control in the Allow column. Press OK twice to apply the changes.

For me, folder was read only. unchecking readonly option fix my problem. Thanks to Zenadix commment

On Windows 10 WSL i got similar issue. The issue was caused by VS code being open and apparently using the file. Closing VS code solved my issue.

TL;DR: Used sudo

In my case, I was running a bash script running on Windows Subsystem for Linux (WSL) as follows:

./generate.sh

The script created a bunch of files however, for reasons unknown, sed was denied permission to modify the permissions on these files for some reason:

The actual sed command was used to perform a search-replace that looked a bit like this:

grep -rl $PATTERN $PUBLIC_API_FOLDER/ \
    | xargs sed -i 's/$PATTERN/$REPLACE/g'

As you can see, despite not having elevated priviledges at any point, I nevertheless was unable to modify the files the script created:

sed: preserving permissions for ‘public_api/models/sedt0qk4D’: Operation not permitted
sed: preserving permissions for ‘public_api/models/sedOxoc1O’: Operation not permitted
sed: cannot rename public_api/models/sedOxoc1O: Permission denied
sed: preserving permissions for ‘public_api/controllers/sedx5BafW’: Operation not permitted
sed: preserving permissions for ‘public_api/models/sedVkdqzc’: Operation not permitted
sed: preserving permissions for ‘public_api/models/sedLvyS3s’: Operation not permitted
sed: cannot rename public_api/models/sedLvyS3s: Permission denied
sed: preserving permissions for ‘public_api/controllers/sedE7GSe8’: Operation not permitted
sed: cannot rename public_api/controllers/sedE7GSe8: Permission denied
sed: preserving permissions for ‘public_api/controllers/sednHZBQf’: Operation not permitted
sed: cannot rename public_api/controllers/sednHZBQf: Permission denied

The solution in my case was to simply run the script with sudo.

sudo ./generate.sh
