csh: manipulating text files - please help!
Hi All,
I am trying to manipulate a text file in a csh script I am writing. I just started scripting a few months ago and have NO idea how to get this to work. My ultimate goal is to turn a text file that looks like this:
4 ep2d_diff_mddw_20_p2-MOD err 128 128 64 62 52611737
2 MPRAGE ok 256 240 160 1 52616379
3 MPRAGERepeat ok 256 240 160 1 52615691
10 AxialPD-T2TSE ok 256 228 48 2 52607078
11 ep2d_bold_moco ok 64 64 36 120 52605446
12 ep2d_bold_moco ok 64 64 36 120 52604109
16 t2_spc_ns_sag_p2_da-fl_iso-MOD ok 256 256 176 1 52602792
Into this:
2 3danat MGZ 002.mgz
3 3danat MGZ 003.mgz
4 diff MGZ 004.mgz
10 AxialPD MGZ 010.mgz
11 ge_funk MGZ 011.mgz
12 ge_funk MGZ 012.mgz
16 t2_space MGZ 016.mgz
Where always,
ep2d_diff_mddw_20_p2-MOD = diff
MPRAGE = 3danat
MPRAGERepeat = 3danat
AxialPD-T2TSE = AxialPD
ep2d_bold_moco = ge_funk
t2_spc_ns_sag_p2_da-fl_iso-MOD = t2_space
The big catch is that the numbers in the first column proceeding these "replacements" may differ between text files so it is impossible to hardcode for example: "2 MPRAGE" is always equal to "2 3danat" because sometimes it might be 3 MPRAGE instead.
So basically, I hope to find any suggestions for commands that might be useful in maintaining the first number in each line, using the second entry in the line to replace it with a new name, then inserting the words "MGZ" next in the line and finally using the number at the beginning of the line as a variable to insert into 00$var.mgz.
Is this even possible???? Or am I hoping for way too much?
Thanks so very very much!

netmasks
netmasks(4) File Formats netmasks(4) NAME
netmasks - network mask database SYNOPSIS
/etc/inet/netmasks /etc/netmasks DESCRIPTION
The netmasks file contains network masks used to implement IP subnetting. It supports both standard subnetting as specified in RFC-950 and variable length subnetting as specified in RFC-1519. When using standard subnetting there should be a single line for each network that is subnetted in this file with the network number, any number of SPACE or TAB characters, and the network mask to use on that network. Network numbers and masks may be specified in the conventional IP `.' (dot) notation (like IP host addresses, but with zeroes for the host part). For example, 128.32.0.0 255.255.255.0 can be used to specify that the Class B network 128.32.0.0 should have eight bits of subnet field and eight bits of host field, in addition to the standard sixteen bits in the network field. When using variable length subnetting, the format is identical. However, there should be a line for each subnet with the first field being the subnet and the second field being the netmask that applies to that subnet. The users of the database, such as ifconfig(1M), perform a lookup to find the longest possible matching mask. It is possible to combine the RFC-950 and RFC-1519 form of subnet masks in the net- masks file. For example, 128.32.0.0 255.255.255.0 128.32.27.0 255.255.255.240 128.32.27.16 255.255.255.240 128.32.27.32 255.255.255.240 128.32.27.48 255.255.255.240 128.32.27.64 255.255.255.240 128.32.27.80 255.255.255.240 128.32.27.96 255.255.255.240 128.32.27.112 255.255.255.240 128.32.27.128 255.255.255.240 128.32.27.144 255.255.255.240 128.32.27.160 255.255.255.240 128.32.27.176 255.255.255.240 128.32.27.192 255.255.255.240 128.32.27.208 255.255.255.240 128.32.27.224 255.255.255.240 128.32.27.240 255.255.255.240 128.32.64.0 255.255.255.192 can be used to specify different netmasks in different parts of the 128.32.0.0 Class B network number. Addresses 128.32.27.0 through 128.32.27.255 have a subnet mask with 28 bits in the combined network and subnet fields (often referred to as the subnet field) and 4 bits in the host field. Furthermore, addresses 128.32.64.0 through 128.32.64.63 have a 26 bits in the subnet field. Finally, all other addresses in the range 128.32.0.0 through 128.32.255.255 have a 24 bit subnet field. Invalid entries are ignored. SEE ALSO
