Scripting Parameter Passing ???

MikeL_4 — Thu, 27 Mar 2003 20:58:48 GMT

I have a script that reads a file similar to:
sql toe_translate_pkb.sql
sql toe_update_pkg.sql
sql tup_$translate_pkg.sql
etc.....

I do a read of the file picking up a parameter for each filed.
i.e. read dir file

I then have to pass these
parameters onto another script, and the problem I am having is the "$" in the filename on some files is being confused for the start of another parameter. So as an end result when I pass $file onto another script the 2nd script translates that to just "tup_"

How do I get around this so the whole file name is passed along ??

Hi:

Escape the dollar sign character with a backslash, as for instance:

# echo \$translate_pkg.sql

Here's the rule:

Let's assume that $X="Bill".

Things inside double quotes get expanded so that "xx$X" becomes "xxBill" BUT things inside single quotes remain intact. 'xx$X' remains "xx$X".

Try using

read -r dir file

"-r" will force read not to interpret the "$".
