Finding a string with another string is found
finding a string with another string is found

EX:

abs c/-

i want to find /-, then copy abs. i know it's easy use awk, but my problem is the substr syntax.

substr($2,2,2) will give me /-

but the conflict is /- is not always the second characted of the second string.

Would this work?
Code:
awk '/\/-/{print $1}' file

thanks! but will it give the same results with:

cat file1 | awk '/\/-/{print $1}' >> file2
# 4  
Old 11-01-2010
Yes the cat is superfluous. It is equivalent to:
Code:
awk '/\/-/{print $1}' file1 >> file2

it worked! thanks!

but i do have a follow up inquiry. my raw data is like this:

123 456 ABS-05
UNIX C/-

i need a result like this:

UNIX 123 456


i used awk' ((substr...) to get 123 456. but i cant put the syntax you gave me to have UNIX. thanks!

Hi, hat is the criterion for your follow up? The first two words on the previous line plus the first word on the current line?
