dirname

My script: #!/usr/bin/env bash PATH=/home/user/example/foo/bar mkdir -p /tmp/backup$PATH And now I want to get first folder of "$PATH": /home/ cd /tmp/backup rm -rf ./home/ cd - > /dev/null How can I always detect the first folder like the example above? "dirname $PATH" just returns "/home/user/example/foo/". Thanks in advance! :) I've found a solution: #/usr/bin/env bash DIRECTORY="/home/user/example/foo/bar" BASE_DIRECTORY=$(echo "$DIRECTORY" | cut -d "/" -f2) echo "#$BASE_DIRECTORY#"; This returns always the first directory. In this example it would return following: #home# Thanks to

The only solution I've encountered is to use regular expressions and recursively replace the first directory until you get a word with no slashes. gsub("/\\w*/","/",gsub("/\\w*/","/",getwd())) Is there anything slightly more elegant? (and more portable?) Your example code doesn't work for me, but you're probably looking for either basename or dirname : > getwd() [1] "C:/cvswork/data" > basename(getwd()) [1] "data" > dirname(getwd()) [1] "C:/cvswork" If you didn't know basename (and I didn't), you could have used this: tail(strsplit(getwd(), "/")[[1]], 1) 来源： https://stackoverflow.com/questions

If I have a file path such as... /home/smith/Desktop/Test /home/smith/Desktop/Test/ How do I change the string so it will be the parent directory? e.g. /home/smith/Desktop /home/smith/Desktop/ dir=/home/smith/Desktop/Test parentdir="$(dirname "$dir")" Works if there is a trailing slash, too. ...but what is "seen here " is broken. Here's the fix: > pwd /home/me > x='Om Namah Shivaya' > mkdir "$x" && cd "$x" /home/me/Om Namah Shivaya > parentdir="$(dirname "$(pwd)")" > echo $parentdir /home/me Clearly the parent directory is given by simply appending the dot-dot filename: /home/smith/Desktop

I have a folder structure as follows: mydomain.com ->Folder-A ->Folder-B I have a string from Database that is '../Folder-B/image1.jpg', which points to an image in Folder-B. Inside a script in Folder-A, I am using dirname( FILE ) to fetch the filename and I get mydomain.com/Folder-A . Inside this script, I need to get a string that says 'mydomain.com/Folder-B/image1.jpg . I tried $path=dirname(__FILE__).'/'.'../Folder-B/image1.jpg'; This shows up as mydomain.com%2FFolder-A%2F..%2FFolder-B%2Fimage1.jpg This is for a facebook share button, and this fails to fetch the correct image. Anyone know

Suppose I have a file /from/here/to/there.txt , and want to get only the last part of its dirname to instead of /from/here/to , what should I do? You can use basename even though it's not a file. Strip off the file name using dirname , then use basename to get the last element of the string: dir="/from/here/to/there.txt" dir="$(dirname $dir)" # Returns "/from/hear/to" dir="$(basename $dir)" # Returns just "to" Using bash string functions: $ s="/from/here/to/there.txt" $ s="${s%/*}" && echo "${s##*/}" to The opposite of dirname is basename : basename "$(dirname "/from/here/to/there.txt")" Pure
