File seen by "ls", but not found by "more"

[chau]

Hi all,

I recently install Mint and overall quite like it (I migrate from Ubuntu). There is a very strange issue that is annoying, though. As indicated in the title, I can find certain files by "ls" but not with more (or vim even create the same a new file with the same name). Have a look at the outcome below:

Code: Select all

chau@X1-Carbon:~$ ls /home/chau/.slinks/gap 
/home/chau/.slinks/gap
chau@X1-Carbon:~$ more /home/chau/.slinks/gap 
more: stat für /home/chau/.slinks/gap ist fehlgeschlagen: Datei oder Verzeichnis nicht gefunden
chau@X1-Carbon:~$ vim /home/chau/.slinks/gap 

(the last command creates a new file)

I also experience a similar problem with Goldendict: I cannot find the folder in Goldendict search window, but also see it with the system Folder Viewer.

This is for me completely strange. The only reason I can think of is that I install Mint as dual boot to Windows and Ubuntu. Maybe the format of the later can influence that indexing files.

Any suggestion for fixing is highly appreciated. Thanks!


Cheers,
Chau

Hello, chau.

Like a lot of users you use the ls command without any options. Pure ls will only list the names of files and folders.
Try the command with the "minus lowercase L" option like follows, please:

Code: Select all

ls -l /home/chau/.slinks/gap 

In this form ls -l will display the name plus more details.
Specifically
+ the object owner,
+ the object owner's group,
+ the access permissions for owner - owner's group - others
should explain, why you are not permitted to view the file with more or to edit it with vim.
more requires read permissions for your account on the object named gap.
vim requires read+write permissions for your account on the object named gap.

HTH,
Karl

Thank you! Here is the output:

Code: Select all

chau@X1-Carbon:~$ ls -l /home/chau/.slinks/gap 
lrwxrwxrwx 1 chau chau 30 Jun 15 22:10 /home/chau/.slinks/gap -> Programs/gap-4.11.1/bin/gap.sh

I think this may be not the reason. Notice that

Code: Select all

vim

creates a completely new file, instead of prompting that I do not have the right to read or edit. (OK, it is a symbolic link, so trying to edit it is a bit strange but I was really trying to test. Also call

Code: Select all

 gap 

in the promt, or using tab when constructing directory, both do not work.)

PS: slinks is in the PATH already

That seems to behave as expected. You have in directory /home/chau/.slinks a symbolic link gap to Programs/gap-4.11.1/bin/gap.sh. Put differently, you have a symbolic link /home/chau/.slinks/gap to /home/chau/.slinks/Programs/gap-4.11.1/bin/gap.sh. I however expect that "Programs" does not in fact live under /home/chau/.slinks but for example directly under /home/chau?

If so you are going to want e.g.

Code: Select all

ln -sf ../Programs/gap-4.11.1/bin/gap.sh ~/.slinks/gap

or if you prefer

Code: Select all

ln -sf ~/Programs/gap-4.11.1/bin/gap.sh ~/.slinks/gap

Oh yes, that was idiot from me! Thanks, that resolves it. I still have problem with Goldendict search folder, but that is probably a problem with Goldendict, I probably should try to ask them first.

Thank you!
