Ubuntu – One-word command to search for a file

Open a terminal and execute this command:

mv  -v ~/Downloads/* ~/Videos/

It will move all the files and folders from Downloads folder to Videos folder.

To move all files, but not folders:

If you are interested in moving all files (but not folders) from Downloads folder to Videos folder, use this command

find ~/Downloads/ -type f -print0 | xargs -0 mv -t ~/Videos

To move only files from the Download folders, but not from sub-folders:

If you want to move all files from the Downloads folder, but not any files within folders in the Download folder, use this command:

find ~/Downloads/ -maxdepth 1 -type f -print0 | xargs -0 mv -t ~/Videos

here, -maxdepth option specifies how deep find should try, 1 means, only the directory specified in the find command. You can try using 2, 3 also to test.

See the Ubuntu find manpage for a detailed explanation

Execute:

find -type f -name "specificFileName" -exec sed -i.bak 's/foundWord/replaceWithWord/' '{}' \;

This will only replace first seen 'foundWord' with 'replaceWithWord', in case you wanted to replace all these 'foundWord's add sed's "g" enabler to having replace all seen

find -type f -name "specificFileName" -exec sed -i.bak 's/foundWord/replaceWithWord/g' '{}' \;

note: This will copies the 'specificFileName's as their backup files and name them with "specificFileName.bak", by dropping the "-i.bak" you will tell 'sed' to inplace replace,
