Full Discussion: Ambiguous redirect error and syntax error when using on multiple files
Operating Systems Linux Ambiguous redirect error and syntax error when using on multiple files Post 302688395 by RudiC on Sunday 19th of August 2012 03:14:08 AM

It would be helpful to post the error messages, maybe embedded in the script's output when run with options -v and/or -x set. For now, I see the following noteworthy:
Code:
for i in "ls -l | grep ^- | awk '{print $9}'"

won't fly. For command substitution use backticks or the $(...) construct instead of double quotes. BTW, there may be better ways than this to eliminate special files.
The
Code:
grep -i "^..............ASPRODUCTSUMMARY"< "$i" > "$i";

will destroy every file in your directory that does not have the grep pattern in it and reduce those who have to the lines containing the pattern. If filenames contain special chars, e.g. space, the ambiguous redirect error may result (not sure though).
The second error you mention will probably be syntax error: unexpected end of file
and is the result of a missing ; in line 19 just in front of the done

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
