script to search for the contents of a file
Hi all,
Please see my requirement and post me asap.
Spool all the tables names into a file . Take each table name and check if it is present in any of the scripts in a directory using grep -il command. The script has to loop through the tables list and take each table and find it's presence in directory. After this exercise, we need to get the list of tables that not present in any of the scripts.
As I am beginner to this shell scripting, I have given the below logic for this to be done. Logic can be same , but I want a clean debugged script.
I am not able to use the variables properly. Please let me know how to use the variables in this case.
Script:
for i in all_tables.txt (this is the spooled file which contains the table names)
do
tbl= head -i all_tables.txt|tail -1
search=grep -il tbl *
if(test -z $search)
then echo ${tbl}>>unused (I wanted to created a file with all the tables which are not used in the scripts)
fi
done
Thanks
Vasundhara

Font::TTF::Ttc(3pm) User Contributed Perl Documentation Font::TTF::Ttc(3pm)
NAME
Font::TTF::Ttc - Truetype Collection class
DESCRIPTION
A TrueType collection is a collection of TrueType fonts in one file in which tables may be shared between different directories. In order
to support this, the TTC introduces the concept of a table being shared by different TrueType fonts. This begs the question of what should
happen to the ' PARENT' property of a particular table. It is made to point to the first directory object which refers to it. It is
therefore up to the application to sort out any confusion. Confusion only occurs if shared tables require access to non-shared tables.
This should not happen since the shared tables are dealing with glyph information only and the private tables are dealing with encoding and
glyph identification. Thus the general direction is from identification to glyph and not the other way around (at least not without
knowledge of the particular context).
INSTANCE VARIABLES
The following instance variables are preceded by a space
fname (P)
Filename for this TrueType Collection
INFILE (P)
The filehandle of this collection
The following instance variable does not start with a space
directs
An array of directories (Font::TTF::Font objects) for each sub-font in the directory
METHODS
Font::TTF::Ttc->open($fname)
Opens and reads the given filename as a TrueType Collection. Reading a collection involves reading each of the directories which go to make
up the collection.
$c->read
Reads a Collection by reading all the directories in the collection
$c->find($direct, $name, $check, $off, $len)
Hunts around to see if a table with the given characteristics of name, checksum, offset and length has been associated with a directory
earlier in the list. Actually on checks the offset since no two tables can share the same offset in a TrueType font, collection or
otherwise.
$c->DESTROY
Closees any opened files by us
BUGS
No known bugs, but then not ever executed!
