I have a tar file: Rel223_NIMS_ASC_PLSQL_20061121_01.tar.gz

I uncompressed the file with:
gunzip Rel223_NIMS_ASC_PLSQL_20061121_01.tar.gz
and it became Rel223_NIMS_ASC_PLSQL_20061121_01.tar

Now i used
tar -xvf Rel223_NIMS_ASC_PLSQL_20061121_01.tar
and unix showed me contents of the above file

$ tar -xvf Rel223_NIMS_ASC_PLSQL_20061121_01.tar
x del_20061121_01, 0 bytes, 0 tape blocks
x del_20061121_01/plsql, 0 bytes, 0 tape blocks
x del_20061121_01/plsql/1_conk_prod_ST.sql, 97337 bytes, 191 tape blocks
x del_20061121_01/plsql/install_nims20061121_01.ksh, 827 bytes, 2 tape blocks
x del_20061121_01/plsql/install_nims20061121_01.sql, 594 bytes, 2 tape blocks
x del_20061121_01/docs, 0 bytes, 0 tape blocks
x del_20061121_01/docs/Rel223_NIMS_ASC_PLSQL_20061121_01_i10.doc, 58880 bytes, 115 tape blocks

All these files are shell, pl/sql files.
I want to read the induvidual files. i.e. i want to read the contents of
del_20061121_01/plsql/install_nims20061121_01.sql etc
how can i do this.

What exactly do you mean by "read the contents"?  Do you mean you want to extract and see the contents of a specified file?

If so, then do

gzip -dc Rel223_NIMS_ASC_PLSQL_20061121_01.tar.gz | tar xf - del_20061121_01/plsql/install_nims20061121_01.sql ; cat del_20061121_01/plsql/install_nims20061121_01.sql

The - in conjunction with the tar -f flag means that the "file" tar is reading from is stdin.

This is useful to pipe tar output to the tar command.

In your original post, you uncompressed the tar file.  There's no need to do that if you do

gzip -dc file.tar.gz | tar xvf -

or if you have a Linux system or system where tar recognises the -z flag, you can simply do

tar zxvf file.tar.gz
