expand: Do not convert tabs after non blanks.
$ expand -i ${filename}
try on your machine
The "expand" command is used to replace tabs in a text file with spaces. The "-i" option tells the command to edit the file in place, which means the changes will be made directly to the original file rather than creating a new file.
The "${filename}" is a placeholder for the actual file name. You need to replace it with the name of the file you want to modify. For example, if you have a file called "example.txt" and you want to replace the tabs with spaces in that file, the command will be:
expand -i example.txt
After executing this command, the tabs in the "example.txt" file will be replaced with spaces.
