Hi there
I'm using gawk 3.1.6 to parse some output from [b]isql [/b](Sybase) that looks
like the following:
[code]
|data_type|type_name |precision |length |scale |
|---------|----------------|-----------|-----------|------|
| 4|int | 10| 4| 0|
| 1|char | 7| 7| NULL|
| 12|varchar | 50| 50| NULL|
| 12|varchar | 35| 35| NULL|
| 12|varchar | 35| 35| NULL|
| 12|varchar | 35| 35| NULL|
| 12|varchar | 35| 35| NULL|
| 12|varchar | 15| 15| NULL|
| 12|varchar | 25| 25| NULL|
| 1|char | 2| 2| NULL|
| 12|varchar | 30| 30| NULL|
| 1|char | 1| 1| NULL|
[/code]
To do so, I am using a regexp FS as follows:
[code]
BEGIN { FS=" *| *"; OFS = "\t" }
{
print $1, $2, $3, $4, $5
}[/code]
The result is that the fields are indeed split on the pipes, but field values
all INCLUDE the pipes as well! Whereas if the pipes are say colons, and i use
FS=" *: *", then i get expected results .. viz: the colons are NOT included
with the field values.
I have tried escaping the pipe (\|) .. but gawk reports that it is not necessary
to do so:
[quote]awk: awk\readpipes.awk:7: warning: escape sequence `\|' treated as plain
`|'[/quote]
Am i doing something wrong, or is this a bug/problem that i need to find a
workaround
for?
TIA
