ls command is interrupted

Consuelo Sierra — Mon, 25 Feb 2002 16:47:20 GMT

When I do "ls -la" from a remote HP workstation of a directory that have a lot of files, the command result is interrupted. Anyone knows if there are a configurable variable or parameter with the maximum number of files that can display the ls command?

Hi,

yes, you are right, the command line parameters of each command are limited to a specific number of characters. I think this is about 5500 characters alltogether for the command line. Simple solution:

create a script and do the listing with a for-construct:

for i in `ls -al $1`
do
ls -al $i
done

usage :
# script_name name_of_directory_to_list

Of course you can pipe this to a more-commmand.

Allways stay on the bright side of life!

Hi:

I don't think there is an inherant limit to the number of files that ls can display BUT there is a limit to the size of the environment space/command line space that the exec() system call can use.

If you cd to the desired directory, then do your ls -la without any files specified, you should be fine.

Hi Consuelo,

of course Clay is right... If you need these listings very open, the following script solves the problem also very easy

cd $1
ls -al
cd -

usage:

# script_name absolute_path_to_directory

Allways stay on the bright side of life!

If you get the following message-

sh: /usr/bin/ls: The parameter list is too long

Then the above solutions should work for you. If you are having a problem because you say you are listing a "remote" workstation, and are using "remsh" to execute the "ls" command, then it could be a different issue (like a networking issue).

Or it could be a dodgy file name on the remote host which contains the end-of-file character - this might cause remsh to close its socket before the rest of the data is pushed thro.

Hi

I would not expect ls -la to have a problem with too much data because it uses no wild cards. You possibly have a network timeout if the link is slow.

Try
remsh node "cd dir;ls -la"|while read line
do
echo "$line"
done
Or
remsh node "cd $dir;ls -la > /tmp/$PPID;cat /tmp/$PPID;/bin/rm /tmp/$PPID"

See if they give breaks

Does the following work?

remsh node "ls -la | cat -v"

If it does, it is definately bad characters in file names.

Hi,

I have the same problem when there is too much files in a directory. But I don't really know the standard limit. For this, I don't list the entire directory but just some part of this.
ls -al A*
ls -al B* ....

I am sure that there is some limit
