Here is a portable (POSIX) solution, i.e. Also, specify the name of the file that contains the text. Just don't use xargs.It is a neat program but it doesn't go well with find when faced with non trivial cases. When used with a directory, any files created inside it will take their group permissions from the directory they're being created in, not from the user who is creating the file. To search for text pattern in a file, simply run grep followed by the pattern name. sed -e s//r/ file.txt This replaces (s) the zero-size area right before the end of the line () with r. If you want to do it with sed, you can insert a carriage return at the end of every line. When this is applied to a file, it means the file will be executed with the privileges of the ower's group. This is exactly what unix2dos does: unix2dos file.txt That will replace file.txt in-place with a version with CRLF line endings. The execution permission for the group can also be an s. ![]() If it is present, it means that the file is executed with the privileges of the file owner, not the user executing the file. Sometimes the execution permission for the owner is represented by an s. The second set of three permissions are for group members, and the last set of three permissions is for others. The first set of three characters are the permissions for the file owner. If the permission is not granted, a hyphen - is shown. ![]() If the permission is granted, there will be an r, w, or x present. Each group of three represent the read, write, and execute permissions, in that order. The next nine characters are three groups of three characters displayed contiguously.
