Perl: Search and print help
Hi all,

I need a bit of help with a perl script,

I have a file containing lines that look like:

M1 (Agnd Agnd ibias_gnP Agnd) nch l=250.0n w=10u m=1 ad=2.5e-12 \
as=2.5e-12 pd=20.5u ps=20.5u nrd=0.025 nrs=0.025 sa=2.5e-07 \
sb=2.5e-07
M21 (Agnd VSSabc Agnd Agnd) nch l=250.0n w=10u m=12 ad=1.83333e-12 \
as=1.83333e-12 pd=13.7u ps=13.7u nrd=0.0183333 nrs=0.0183333 \
sa=5.52857e-07 sb=5.52857e-07
M18 (Agnd Vddxyz ibias_eqN Agnd) nch l=250.0n w=10u m=1 ad=2.5e-12 \
as=2.5e-12 pd=20.5u ps=20.5u nrd=0.025 nrs=0.025 sa=2.5e-07 \
sb=2.5e-07
M0 (Agnd Agnd net133 Agnd) nch l=250.0n w=10u m=1 ad=2.5e-12 \
as=2.5e-12 pd=20.5u ps=20.5u nrd=0.025 nrs=0.025 sa=2.5e-07 \
sb=2.5e-07
M32 (net120 VDDcde ibias_gnN Agnd) nch l=250.0n w=10u m=7 ad=1.64286e-12 \
as=1.64286e-12 pd=11.7571u ps=11.7571u nrd=0.0164286 nrs=0.0164286 \
sa=1.06144e-06 sb=1.06144e-06
M8 (Agnd Agnd ibias_eqP Agnd) nch l=250.0n w=10u m=1 ad=2.5e-12 \
as=2.5e-12 pd=20.5u ps=20.5u nrd=0.025 nrs=0.025 sa=2.5e-07 \
sb=2.5e-07

I need the script to search for Agnd or VSS or Vss or vss or VDD or Vdd or vdd in the second position (ie the gate) inside the bracket.
in other words

M32 (net120 VDDcde ibias_gnN Agnd) => match
M42 (net120 net20 ibias_gnN Agnd) => no match
When a match is found it needs to print off the line to a file

Code:
print if m/\(\S+\s+(Agnd|V(SS|ss|DD|dd))\s/

# 3

seeing that they all appear in column 3,
Code:
awk '$3~/Agnd|V(SS|ss|DD|dd)/' file

likewise, in Perl, split the line, get item 3 and compare with the regex
