UNIX for Dummies Questions & Answers

i have a cd of pdf and chm documents that i transfered from my windows xp box. i transfered the files to my linux box (ubuntu hardy). unfortunately, i used to be a windows GUI only user so the use of spaces and "( )" and underscores. now that i use linux, ive been using CLI for using and moving/coping files. when i tried to view a .chm file, i had installed chmsee for those files, i got problems saying that the use of "(" isnt allowed. is there anyway in the terminal to use those files in such a fashion like, for example, the file "Linux file (2005).chm", and use "mv" the change the name without having to use GUI. something like this:
"mv Linux file (2005).chm Linux_file_2005.chm"
is this possible???

You just need to escape or double quote the special characters on the command line. In my experience, Bash does this for you automatically with tab completion, although there are some minor glitches.

The only characters you absolutely cannot use in a file name are slash (because it's used to separate directories) and ASCII null (because it's used internally to terminate strings).

Here's a quick attempt at batch rename.

Code:

for f in *; do
  case $f in *[!A-Za-z0-9_-]*)  mv -i "$f" "`echo "$f" | tr " " _ | tr -dc A-Za-z0-9_-`";; esac
done

This might be even a little bit too conservative in what characters it will accept in a file name, but at least it's a start.

ok
i used the double quotes around the original file name and then changed it with underscores. thanks for the tip.

Code:

for ex: linux books 2005.chm
$mv "linux books 2005.chm" linux_books_2005.chm

the only problems i have is that im trying to open the files up with ChmSee via terminal

Code:

chmsee linux_books_2005.chm

the problem is i get this

Code:

chmsee: error while loading shared libraries: libxul.so: cannot open shared object file: No such file or directory

should i get another viewer or is there a way to get the libxul.so file

If you installed chmsee from an Ubuntu repository, it should have pulled in any packages it depends on.

Code:

vnix$ apt-file search libxul.so
libxul-dev: usr/lib/libxul.so
libxul0d: usr/lib/libxul.so.0d
libxul0d: usr/lib/xulrunner/libxul.so
libxul0d-dbg: usr/lib/debug/usr/lib/libxul.so.0d
xulrunner-1.9: usr/lib/xulrunner-1.9a8/libxul.so
xulrunner-1.9-dev: usr/lib/xulrunner-devel-1.9a8/sdk/lib/libxul.so

If you just want the library, I guess you should linstall libxul0d, although it's of course somewhat likely that the exact version is not what chmsee wants.

(XUL is the Mozilla toolkit, XULrunner is basically Mozilla without the actual browser -- can be useful for running Chatzilla as a separate process, for example.)
