Hello,
I tried to modify Russ' script below to be usable on p9p. I came up with
------------------------------------
#!/usr/local/plan9/bin/rc
if(! ~ $#* 1) {
echo 'usage: Run title' >[1=2]
exit 1
}
id=`{awk -v 'pat='$1 '$6 ~ pat {print $1}' <{9p read acme/index}}
if(~ $#id 0) {
echo 'no match for pattern' >[1=2]
exit 2
}
if(! ~ $#id 1) {
echo 'ambiguous pattern' >[1=2]
exit 3
}
if(~ `{wc -w <{9p read acme/$id/rdsel}} 0) {
echo 'no command selected' >[1=2]
exit 4
}
#exec cat <{9p read acme/$id/rdsel}
exec /usr/local/plan9/bin/rc <{9p read acme/$id/rdsel}
------------------------------------
but the last line doesn't really do what I want, yielding the error:
Run: exit 1
rc: /dev/fd/5:2: token EOF: syntax error
can anybody help me with what is wrong?
The commented-out line with cat prints correctly what I have
selected in the other window (see the description of the original
script), e.g.
>awk '{print $2}'
Thank you!
Ruda
