If I run touch non/existing/folder/my-file.txt, touch complains about non-existing folders.
Can I create these folders on the same command, similar to mkdir -p?
No, but you can write a script that does that:
# new.sh
for file; do
[[ $file =~ ((.+\/)*)(.+) ]] && mkdir -p "${BASH_REMATCH[2]}"
touch $file
done
Then run: ./new.sh non/existing/folder/my-file.txt possibly/other/files.txt

I want to copy the functionality of a windows program called files2folder, which basically lets you right-click a bunch of files and send them to their own individual folders.
So
1.mkv 2.png 3.doc
gets put into directories called
1 2 3
I have got it to work using this script but it throws out errors sometimes while still accomplishing what I want
#!/bin/bash
ls > list.txt
sed -i '/list.txt/d' ./list.txt
sed 's/.$//;s/.$//;s/.$//;s/.$//' ./list.txt > list2.txt
for i in $(cat list2.txt); do
mkdir $i
mv $i.* ./$i
done
rm *.txt
is there a better way of doing this? Thanks
EDIT: My script failed with real world filenames as they contained more than one . so I had to use a different sed command which makes it work. this is an example filename I'm working with
Captain.America.The.First.Avenger.2011.INTERNAL.2160p.UHD.BluRay.X265-IAMABLE
I guess you are getting errors on . and .. so change your call to ls to:
ls -A > list.txt
-A List all entries except for . and ... Always set for the super-user.
You don't have to create a file to achieve the same result, just assign the output of your ls command to a variable. Doing something like this:
files=`ls -A`
for file in $files; do
echo $file
done
You can also check if the resource is a file or directory like this:
files=`ls -A`
for res in $files; do
if [[ -d $res ]];
then
echo "$res is a folder"
fi
done
This script will do what you ask for:
files2folder:
#!/usr/bin/env sh
for file; do
dir="${file%.*}"
{ ! [ -f "$file" ] || [ "$file" = "$dir" ]; } && continue
echo mkdir -p -- "$dir"
echo mv -n -- "$file" "$dir/"
done
Example directory/files structure:
ls -1 dir/*.jar
dir/paper-279.jar
dir/paper.jar
Running the script above:
chmod +x ./files2folder
./files2folder dir/*.jar
Output:
mkdir -p -- dir/paper-279
mv -n -- dir/paper-279.jar dir/paper-279/
mkdir -p -- dir/paper
mv -n -- dir/paper.jar dir/paper/
To make it actually create the directories and move the files, remove all echo
This question already has answers here:
Why can't I change directories using "cd" in a script?
(33 answers)
Closed 3 years ago.
I'm fairly new to bash scripting.
I'm trying to create a directory with a timestamp and then cd into the directory.
I'm able to create a directory and can cd into it the directory with one command.
mkdir "build" && cd "build"
I can create the directory with data then cd into it.
mkdir date '+%m%d%y' && cd date '+%m%d%y' I am able to create this dir and cd into it with one command.
Here is my bash script:
#!/bin/bash
# mkdir $(date +%F) && cd $(date +%F)
mkdir build_`date '+%m%d%y'` && cd build_`date '+%m%d%y'`
I need to create the directory with build_date '+%m%d%y' in the title then cd into that folder.
I've looked online but am unable to come up with a solution.
Thank you.
Try this:
#!/bin/bash
build_dir="build_$(date '+%m%d%y')"
mkdir $build_dir && cd $build_dir
Best is to name your Folders YYYY.MM.DD like build_2019.11.21
#!/bin/bash
DIRECTORY="build_$(date '+%Y.%m.%d')"
if [ ! -d "$DIRECTORY" ]; then
# checking if $DIRECTORY doesn't exist.
mkdir $DIRECTORY
fi
cd $DIRECTORY
touch testfile
Here's a script that uses /usr/bin/env bash and the builtin command printf instead of /bin/date.
#!/usr/bin/env bash
date="$(printf '%(%m%d%y)T' -1)"
[[ -d build_"${date}" ]] || mkdir build_"${date}"
cd build_"${date}"
# do something useful here
# ...
However, changing directory in a script (subshell) is not much use on its own, as your current working directory ($PWD) will be the same after the script exits.
If you want to have the current shell session change into the new directory, use a shell function.
mkbuild() {
date="$(printf '%(%m%d%y)T' -1)"
[[ -d build_"${date}" ]] || mkdir build_"${date}"
cd build_"${date}"
}
Then run it:
$ echo $PWD
/tmp
$ mkbuild
$ echo $PWD
/tmp/build_112119
mkdir $(date '+%d-%b-%Y')
then cd to the dynamically created directory
How to "cd" to a directory which is created using "mkdir $(date '+%d-%b-%Y')" and do the operations by moving into the created directory in bash script
Simple way would be, you store the directory name in a variable
dirname=$(date '+%d-%b-%Y')
if [ -n "$dirname" ]; then
mkdir "$dirname"
if [ -d "$dirname" ]; then
cd "$dirname"
fi
fi
Added some error handling and also if your file is written in Windows and being run in an unix environment or vice-versa, I would recommend using dos2unix which will handle the new line character conversions (this is for the ? characters OP is seeing in ls).
Can you show me your case?
In most cases, you should not cd in to the directory. Use absolute path instead:
Good practice:
mkdir /tmp/mydir/
cp -R /usr/local/example/ /tmp/mydir/
sed 's/foo/bar/g' /tmp/mydir/afile
Bad practice:
mkdir /tmp/mydir/
cd /tmp/mydir/
cp -R /usr/local/example/ .
sed 's/foor/bar/g' afile
P.S.
Subj:
$ mkdir $(date '+%d-%b-%Y')
$ cd $(date '+%d-%b-%Y')
$ pwd
/Users/user/18-Feb-2019
In Bash, $_ expands to the last argument to the previous command. So you could do:
mkdir $(date '+%d-%b-%Y')
cd $_
In a real Bash program you would want to quote the expansions (use Shellcheck on your code to check for missing quotes), and check for errors on both mkdir and cd.
I have a shell (ksh) script. I want to determine whether a certain directory is present in /tmp, and if it is present then I have to delete it. My script is:
test
#!/usr/bin/ksh
# what should I write here?
if [[ -f /tmp/dir.lock ]]; then
echo "Removing Lock"
rm -rf /tmp/dir.lock
fi
How can I proceed? I'm not getting the wanted result: the directory is not removed when I execute the script and I'm not getting Removing Lock output on my screen.
I checked manually and the lock file is present in the location.
The lock file is created with set MUTEX_LOCK "/tmp/dir.lock" by a TCL program.
In addition to -f versus -d note that [[ ]] is not POSIX, while [ ] is. Any string or path you use more than once should be in a variable to avoid typing errors, especially when you use rm -rf which deletes with extreme prejudice. The most portable solution would be
DIR=/tmp/dir.lock
if [ -d "$DIR" ]; then
printf '%s\n' "Removing Lock ($DIR)"
rm -rf "$DIR"
fi
For directory check, you should use -d:
if [[ -d /tmp/dir.lock ]]; then
echo "Removing Lock"
rm -rf /tmp/dir.lock
fi
How can I have the following command
echo "something" > "$f"
where $f will be something like folder/file.txt create the folder folder if does not exist?
If I can't do that, how can I have a script duplicate all folders (without contents) in directory 'a' to directory 'b'?
e.g if I have
a/f1/
a/f2/
a/f3/
I want to have
b/f1/
b/f2/
b/f3/
The other answers here are using the external command dirname. This can be done without calling an external utility.
mkdir -p "${f%/*}"
You can also check if the directory already exists, but this not really required with mkdir -p:
mydir="${f%/*}"
[[ -d $mydir ]] || mkdir -p "$mydir"
echo "something" | install -D /dev/stdin $f
try
mkdir -p `dirname $f` && echo "something" > $f
You can use mkdir -p to create the folder before writing to the file:
mkdir -p "$(dirname $f)"
