As specified in title I am looking for a way how to create links to all subfolders containing specified text in their names, so for example for all subfolders of root directory containing ".app" in their names an link will be created to "/AppLinks" directory. I would like to use it in bash script (open source, free).
Does anyone know how to do that?
I searched it by google with no luck.
find yourdir -type d -name '*.app' -exec ln -s {} /AppLinks \;
Find all directories named something.app in yourdir, and create a symlink to them in /AppLinks.
single line bash-fu
function FUNCsymlink() { echo "$1"; fileName=`basename "$1"`; ln -s "$1" "/AppLinks/$fileName"; }; export -f FUNCsymlink; find `pwd`/ -maxdepth 1 -type d -iname "*.app" -exec bash -c "FUNCsymlink '{}'" \;
to easy reading:
function FUNCsymlink() {
echo "$1";
fileName=`basename "$1"`;
ln -s "$1" "/AppLinks/$fileName";
};
export -f FUNCsymlink;
find `pwd`/ -maxdepth 1 -type d -iname "*.app" -exec bash -c "FUNCsymlink '{}'" \;
you may have to adjust it a bit for your specific solution.
wherever you run it, it will create the symlinks to /AppLinks
it will only look for direct subfolders, not subfolders of subfolders, thats what I believe you need..

I am trying to copy a folder containing a subfolder structure, while excluding a specified subfolder by using the find -exec cp command. I have managed to use multiple working excluding options when I am using the find command alone, but once I add the '-exec cp' command, the excluding terms work no longer.
Imagine the directory of interest containing multiple files and subfolders, with one subfolder named "exclusion_string"
This find command works properly when used alone:
find ~/directory/of/interest/ -maxdepth 2 ! -name "*exclusion_string*"
... while this command negates the exclusion criterium:
find ~/directory/of/interest/ -maxdepth 2 ! -name "*exclusion_string*" -exec cp -r '{}' . \;
Likewise, when using other criteria or arguments, the exclusion of a subdirectory is lost, E.g:
find ~/directory/of/interest/ -maxdepth 2 -name "*" -size -100k -exec cp -r '{}' . \;
find ~/directory/of/interest/ -maxdepth 2 -name "*exclusion_string*" | xargs cp -rt .
What am I missing here?
So I have a find command as below which finds the libclntsh.so.* files in a directory instantclient.
find instantclient -type f -name "*libclntsh\.so\.[0-9]*\.[0-9]*"
This results in for e.g.,
instantclient/libclntsh.so.11.1
How do I now ln within instantclient directory, ln -s libclntsh.so.11.1 libclntsh.so all with a find command in combination with exec
I should mention here that I DO NOT want to cd into instantclient.
And this is for Alpine Linux.
Use the -execdir option. As per manual:
-execdir command {} ;
Like -exec, but the specified command is run from the subdirectory containing the matched file, which is not normally the directory in which you started find. This a much more secure method for invoking commands, as it avoids race conditions during resolution of the paths to the matched files.
So your command will be:
find instantclient -type f -name "*libclntsh\.so\.[0-9]*\.[0-9]*" -execdir ln -s {} libclntsh.so \;
EDIT:
Another solution
find instantclient -type f -name "*libclntsh\.so\.[0-9]*\.[0-9]*" | xargs -I {} sh -c 'ln -s $(basename {}) instantclient/libclntsh.so'
I have multiple sites that user my own template, now I have updated my template and I want to update the template using find.
if I do
find . -name template.css -print -exec cp NEW_FILE {} \;
Then all other template.css wil overwritten to.
I only want template.css to be overwritten if they are in the directory mytemplate/css.
Any one an idea?
Example:
/site1/templates/mytemplate/css/template.css*
/site1/templates/othertemplate/css/template.css
/site1/templates/other2template/css/template.css
/site2/templates/mytemplate/css/template.css*
/site2/templates/othertemplate/css/template.css
/site2/templates/other2template/css/template.css
/site3/templates/mytemplate/css/template.css*
/site3/templates/othertemplate/css/template.css
/site3/templates/other2template/css/template.css
The files with an * should only be overwritten
You can use -wholename flag and proper regular expression. This should work for your example:
find . -wholename "*/mytemplate/css/template.css" -print -exec cp NEW_FILE {} \;
I tried to rename files ending with ".txt" to ".abc" using the find command as below. Now the files are not available on my disk.
find ./ -type f -iname '*.txt' -exec sh -c 'mv "$0" "$1.abc"' {} \;
can someone explain me the above command in detail what is did with the files.
Is there any possibility to retrive those, if yes how ?
You used the wrong variable and most of the files cannot be retrieved.
find ./ -type f -iname '*.txt' -exec sh -c 'mv "$0" "$1.abc"' {} \;
will rename every .txt file to a file called .abc. So if you files named bar.txt and foo.txt it will rename bar.txt to .abc and then rename foo.txt to .abc which will overwrite the original contents of bar.txt. You cannot see the file because it is .abc and is hidden under a normal list. If you run 'ls -a' you will see a file named ".abc" which will have the contents of the last .txt file that was renamed.
I am not sure how to do exactly what you wanted but running
find ./ -type f -iname '*.txt' -exec sh -c 'mv "$0" "$0.abc"' {} \;
will rename each .txt file to a .txt.abc file. So you would have bar.txt.abc and foo.txt.abc
The explanation of rondo is correct.
But what are the solutions for your problem?
If you want to replace the suffix .txt with .abc you can use rename
You will have success, if you use rename and find like this:
find . -type f -iname '*.txt' -print0 | xargs -0 rename .txt .abc
For all files found by find like x.txt or a/b.txt the appropriate command will execute, e.g.
rename .txt .abc x.txt
rename .txt .abc a/b.txt
so x.txt -> x.abc, and a/b.txt -> a/b.abc
If you only want to add the suffix .abc to all files you can still use mv
find . -type f -iname '*.txt' -print0 | xargs -0 mv {} {}.abc
With xargs for each file the command mv is executed.
BTW: with the find option "-print0" and the xargs option "-0" the commands work also with filenames which includes spaces.
How to copy a file to several directories of the form *Co*? or *52?
Apparently, just typing
cp fileA *Co*
won't work.
My other concern is that if a directory already contains fileA, I don't want it to be overwritten. That is, if the directory *Co* contains fileA, do NOT copy. Is there a one line solution for this, since I think writing a script with if-else is an overkill.
Thanks!
If your version of cp supports -n, you can do:
find . -name '*Co*' -exec cp -n fileA {} \;
If not:
find . -name '*Co*' -exec sh -c 'test -f $0/fileA || cp fileA $0' {} \;
Note that these will each descend recursively: if you don't want that you can limit the scope of find. To find either Co or *52, you can do:
find . \( -name '*Co*' -o -name '*52' \) -exec ...
