Unix - create path of folders and file - linux

Question

I know you can do mkdir to create a directory and touch to create a file, but is there no way to do both operations in one go?
i.e. if I want to do the below when the folder other does not exist:
cp /my/long/path/here/thing.txt /my/other/path/here/cpedthing.txt
Error:
cp: cannot create regular file `/my/other/path/here/cpedthing.txt': No such file or directory
Has anyone come up with a function as a workaround for this?

Answer 1

Use && to combine two commands in one shell line:
COMMAND1 && COMMAND2
mkdir -p /my/other/path/here/ && touch /my/other/path/here/cpedthing.txt
Note: Previously I recommended usage of ; to separate the two commands but as pointed out by #trysis it's probably better to use && in most situations because in case COMMAND1 fails COMMAND2 won't be executed either. (Otherwise this might lead to issues you might not have been expecting.)

Answer 2

You need to make all of the parent directories first.
FILE=./base/data/sounds/effects/camera_click.ogg
mkdir -p "$(dirname "$FILE")" && touch "$FILE"
If you want to get creative, you can make a function:
mktouch() {
if [ $# -lt 1 ]; then
echo "Missing argument";
return 1;
fi
for f in "$#"; do
mkdir -p -- "$(dirname -- "$f")"
touch -- "$f"
done
}
And then use it like any other command:
mktouch ./base/data/sounds/effects/camera_click.ogg ./some/other/file

Do it with /usr/bin/install:
install -D /my/long/path/here/thing.txt /my/other/path/here/cpedthing.txt
when you don't have a source file:
install -D <(echo 1) /my/other/path/here/cpedthing.txt

Answer 4

This is what I would do:
mkdir -p /my/other/path/here && touch $_/cpredthing.txt
Here, the $_ is a variable that represents the last argument to the previous command that we executed in line.
As always if you want to see what the output might be, you can test it by using the echo command, like so:
echo mkdir -p /code/temp/other/path/here && echo touch $_/cpredthing.txt
Which outputs as:
mkdir -p /code/temp/other/path/here
touch /code/temp/other/path/here/cpredthing.txt
As a bonus, you could write multiple files at once using brace expansion, for example:
mkdir -p /code/temp/other/path/here &&
touch $_/{cpredthing.txt,anotherfile,somescript.sh}
Again, totally testable with echo:
mkdir -p /code/temp/other/path/here
touch /code/temp/other/path/here/cpredthing.txt /code/temp/other/path/here/anotherfile /code/temp/other/path/here/somescript.sh

Answer 5

#!/bin/sh
for f in "$#"; do mkdir -p "$(dirname "$f")"; done
touch "$#"

Answer 6

you can do it in two steps:
mkdir -p /my/other/path/here/
touch /my/other/path/here/cpedthing.txt

Answer 7

as I saw and test in a unix forum this solves the problem
ptouch() {
for p in "$#"; do
_dir="$(dirname -- "$p")"
[ -d "$_dir" ] || mkdir -p -- "$_dir"
touch -- "$p"
done
}

Answer 8

if [ ! -d /my/other ]
then
mkdir /my/other/path/here
cp /my/long/path/here/thing.txt /my/other/path/here/cpedthing.txt
fi

Answer 9

no need for if then statements...
you can do it on a single line usign ;
mkdir -p /my/other/path/here;cp /my/long/path/here/thing.txt /my/other/path/here/cpedthing.txt
-- or on two lines --
mkdir -p /my/other/path/here
cp /my/long/path/here/thing.txt /my/other/path/here/cpedthing.txt
-- the -p prevents error returns if the directory already exists (which is what I came here looking for :))

Answer 10

In the special (but not uncommon) case where you are trying to recreate the same directory hierarchy, cp --parents can be useful.
For example if /my/long contains the source files, and my/other already exists, you can do this:
cd /my/long
cp --parents path/here/thing.txt /my/other

if you want simple with only 1 param snippet :
rm -rf /abs/path/to/file; #prevent cases when old file was a folder
mkdir -p /abs/path/to/file; #make it fist as a dir
rm -rf /abs/path/to/file; #remove the leaf of the dir preserving parents
touch /abs/path/to/file; #create the actual file
