Your sed construct will print the entire first line, that's it. To gather the first word (into another file), use sth like
Code:
 sed  's/^\([^ \t]*\).*/\1/' file

It will collect any non-space char (i.e. the first word) at the start of line, and then the rest of the line, replace the line with those non-spaces, and print.
Thanks RudiC but I'm already using this:
Code:
address=$(echo "http://www.google.com/finance/getprices?i=60&p=1d&f=d,o,h,l,c,v&df=cpct&q=")

#read the name of each SP500 company
symbolsList=$(awk '{print $1}' ../data/SP500symbols.txt)

for symbol in $symbolsList
do 
  echo $symbol;
  fullAdd=$(echo $address$symbol)
  
#curl -o saveDir httpAddr

done

It's simple and works fine.

Not only need to think a little on how to use curl and make the script run every day to save the data files.

Nice Sunday!

NAME
Locale::Script - standard codes for script identification SYNOPSIS
use Locale::Script; $script = code2script('phnx'); # 'Phoenician' $code = script2code('Phoenician'); # 'Phnx' $code = script2code('Phoenician', LOCALE_CODE_NUMERIC); # 115 @codes = all_script_codes(); @scripts = all_script_names(); DESCRIPTION
The "Locale::Script" module provides access to standards codes used for identifying scripts, such as those defined in ISO 15924. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 15924 four-letter codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying scripts. The ones currently supported are: alpha This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician. This code set is identified with the symbol "LOCALE_SCRIPT_ALPHA". The Zxxx, Zyyy, and Zzzz codes are not used. This is the default code set. numeric This is a set of three-digit numeric codes from ISO 15924 such as 115 for Phoenician. This code set is identified with the symbol "LOCALE_SCRIPT_NUMERIC".
