A simple shell prog problem
Posted by manoj [send private reply] at September 10, 2002, 01:27:34 PM Here is a shell prog : eid
for STR in $*
If I run it as : eid A B C
o/ps are A@hotmail.com etc.
If I run it as eid < names
where names is a file containing some strings. it dooesn't work. What is the problem?
Also, if it can't be done this way, can it be done anyhow without using gawk etc.
PS:I'm new to shell prog
Posted by Psion [send private reply] at September 10, 2002, 02:30:39 PM Using < names hooks standard input up to the file `names'. i.e., "prog < names" runs prog with no parameters, and then acts as if you typed the contents of `names' on the kyeboard. $* looks at command line arguments, which is something completely different.
Posted by buzgub [send private reply] at September 10, 2002, 11:59:47 PM something like:
eid `cat names`
may do what you want. If it doesn't, try replacing all the newlines in 'names' with spaces.
