Hello,
Going through book, "Guide to UNIX Using Linux". I am doing one of the projects that has me writing scripts to join files. Here is my pnumname script and I am extracting the programmers names and numbers from the program file and redirecting the output to the file pnn. I then created a joinall script where I am trying to join the files pnn and pnumname and redirect the output to pactrep ( join -t: a1 -j1 1 -j2 1 pnn pnum > pactrep)When I run the script sh joinall and use less to display the contents of the redirected file pactrep, I get an error- join: extra operand `pnum'
Try `join --help' for more information.... I went to the man pages but I still (obvious) do not have a solid grasp. Thanks for the help in advance.
#=======================================================
# Script Name: pnumname
# By: J.D.
# Date: February 2011
# Purpose: Extract Programmer Numbers and Names
#=======================================================
cut -d: -f1-4 programmer | sort -t: -k 1 | uniq > pnn
# The above cuts out fields 1 through 4.
# The output is piped to a sort by programmer number.
# The sorted output is piped to uniq to remove
# duplicates.
# Uniq redirects the output to pnn.
output file pnn results...
cat pnn
