Top Forums Shell Programming and Scripting How to handle variable with special character? Post 303026250 by Corona688 on Thursday 22nd of November 2018 10:11:12 AM

Pseudocode which doesn't do what you want really doesn't tell us what you do want. What is $1 here? And what is 'grep $1' for? It's not going to do anything where you've put it.

Also, I noted above that [ -f * ] is a bad idea since it will fail with syntax errors whenever you match more than one file.

Also, you're still not quoting any of your variables and really should be.

Name
       mbadblocks - tests a floppy disk, and marks the bad blocks in the FAT

Note of warning
       This  manpage  has been automatically generated from mtools's texinfo documentation, and may not be entirely accurate or complete.  See the
       end of this man page for details.

Description
       The mbadblocks command is used to scan an MS-DOS floppy and mark its unused bad blocks as bad. It uses the following syntax:

       mbadblocks drive:

       Mbadblocks scans an MS-DOS floppy for bad blocks. All unused bad blocks are marked as such in the FAT. This is intended to  be  used  right
       after mformat.  It is not intended to salvage bad disks.

Bugs
       Mbadblocks  should  (but  doesn't  yet :-( ) also try to salvage bad blocks which are in use by reading them repeatedly, and then mark them
       bad.

Viewing the texi doc
       This manpage has been automatically generated from mtools's texinfo documentation. However, this process is only  approximative,  and  some
       items, such as crossreferences, footnotes and indices are lost in this translation process.  Indeed, these items have no appropriate repre-
       sentation in the manpage format.  Moreover, not all information has been translated into the manpage version.  Thus I strongly  advise  you
       to use the original texinfo doc.  See the end of this manpage for instructions how to view the texinfo doc.

       *      To generate a printable copy from the texinfo doc, run the following commands:

		     ./configure; make dvi; dvips mtools.dvi

       *      To generate a html copy,	run:

		     ./configure; make html

       A premade html can be found at `http://www.gnu.org/software/mtools/manual/mtools.html'

       *      To generate an info copy (browsable using emacs' info mode), run:

		     ./configure; make info

       The  texinfo  doc looks most pretty when printed or as html.  Indeed, in the info version certain examples are difficult to read due to the
       quoting conventions used in info.
