>Description:
regexp matching in awk/nawk:
if (c !~ /[a-zA-Z]/)
when var c is set to value "0++" or "000"
c ~ /[a-zA-Z]/ results in 1
c !~ /[a-zA-Z]/ results in 0
like when c contains a normal word.
>How-To-Repeat:
1)
simple test:
#!/usr/bin/awk
/[a-zA-Z]/ {
print "Has a Letter: " $0
}
/[A-Z]/ {
print "Has a big Letter: " $0
}
/[a-z]/ {
print "Has a small Letter: " $0
}
every String matches the first and third command.
samples:
Has a Letter:
Has a small Letter:
1
Has a Letter: 1
Has a small Letter: 1
a
Has a Letter: a
Has a small Letter: a
A
Has a Letter: A
Has a big Letter: A
Has a small Letter: A
C
Has a Letter: C
Has a big Letter: C
Has a small Letter: C
Z
Has a Letter: Z
Has a big Letter: Z
Has a small Letter: Z
]
Has a Letter: ]
Has a small Letter: ]
2)
start regression test (without install) in:
$ cd /usr/porst/news/cnews && make
$ cd /usr/porst/news/cnews && make test
output:
: namecheck.awk
test " `echo | awk -f namecheck.awk`" = " empty name" ;
test " `echo a b | awk -f namecheck.awk`" = " white space in name" ;
test " `echo 'a b' | awk -f namecheck.awk`" = " white space in name" ;
test " `(echo a ; echo b) | awk -f namecheck.awk`" = " newline(s) in name" ;
chmod +x namecheck.r
sed -n '/^[^#]/p' namecheck.t >tmp.nc
./namecheck.r <tmp.nc

saw:
not: name component does not contain letter
