Add string end of line
Hello
How can I add a string (always the same) at the end of a specific line in a file...
The file is:

Code:
000000001 041   L $$aspa
000000001 088   L $$aJ.E.N. 551
000000001 090   L $$aINFORMES JEN
000000001 100   L $$aautor 1
----
000000002 041   L $$aeng
000000002 088   L $$aJ.E.N. 1
000000002 090   L $$aINFORMES
000000002 100   L $$aautor2

Then I would like to add this $$cData at the end of the autor line for each records
Like this:

Code:
000000002 100   L $$aautor2$$cData

I try with sed:

Code:
sed -i '/$[0-9]\{9\} 100/$$cData/' luis.dat

But I have an error
Code:
sed: -e expression #1, char 18: unknown command: `$'

Thanks to help

Code:
#  sed '/aautor/s/\(.*\)/\1$$cData/' infile
000000001 041   L $$aspa
000000001 088   L $$aJ.E.N. 551
000000001 090   L $$aINFORMES JEN
000000001 100   L $$aautor 1$$cData
----
000000002 041   L $$aeng
000000002 088   L $$aJ.E.N. 1
000000002 090   L $$aINFORMES
000000002 100   L $$aautor2$$cData

or awk:

Code:
#  awk '/autor/{print $0"$$cData"}!/autor/{print}' infile 
000000001 041   L $$aspa
000000001 088   L $$aJ.E.N. 551
000000001 090   L $$aINFORMES JEN
000000001 100   L $$aautor 1$$cData
----
000000002 041   L $$aeng
000000002 088   L $$aJ.E.N. 1
000000002 090   L $$aINFORMES
000000002 100   L $$aautor2$$cData

Hello
sorry for the confusion

the autor are not :aautor...but could be

Code:
000000001 100   L $$aPEPITO 1$$cData

000000001 100   L $$aLUIS 1$$cData
000000001 100   L $$aPEDRO 1$$cData

Etc... So in the sed command I must put what exactly?
This for example?
Code:
sed '/a*/s/\(.*\)/\1$$cData/' infile



---------- Post updated at 01:47 PM ---------- Previous update was at 01:44 PM ----------

Ha yes some ting important, only lines with field 100 have to be updated, no all the others.


So in this exemple:

Code:
000000001 088   L $$aJ.E.N. 551
000000001 090   L $$aINFORMES JEN
000000001 100   L $$aROMERO, L.

Only this line have to be changed like this:
Code:
000000001 100   L $$aROMERO, L.$$cData

Thanks

Is this what you want?
Code:
awk '$2==100{print $0 "$$cData"}' file

Hi
mmmm not exactly

look if I apply this command I have a file with this:

000000119 100 L $$aRUIZ SAENZ DE MIERA, A.$$cData
000000120 100 L $$aKIM, D.$$cData
000000121 100 L $$aMIKKELSEN, D.R.$$cData

So only field 100...But all the other fields have disapear.
Look a template of the original file:

Code:
000000001 LDR   L ^^^^^nam^^2200325Iia^45e0
000000001 022   L $$a0081-3397
000000001 041   L $$aspa
000000001 088   L $$aJ.E.N. 551
000000001 090   L $$aINFORMES JEN
000000001 100   L $$aROMERO, L.
000000001 245   L $$aCODIGO "REX" PARA AJUSTE DE DATOS EXPERIMENTALES A FUNCIONES EXPONENCIALES Y SU REPRESENTACION GRAFICA
000000001 250   L $$a1 ED
000000001 260   L $$aMADRID:$$b JUNTA DE ENERGIA NUCLEAR,$$c1983
000000001 300   L $$a58 P. + 5 REFERENCIAS BIBLIOGR., 1 H. DE FICHAS CON REFERENCIA BIBLIOGRAFICA Y RESUMEN DEL INFORME
000000001 340   L $$aPAPEL
....

That I want is this:

Code:
000000001 LDR   L ^^^^^nam^^2200325Iia^45e0
000000001 022   L $$a0081-3397
000000001 041   L $$aspa
000000001 088   L $$aJ.E.N. 551
000000001 090   L $$aINFORMES JEN
000000001 100   L $$aROMERO, L.$$cData
000000001 245   L $$aCODIGO "REX" PARA AJUSTE DE DATOS EXPERIMENTALES A FUNCIONES EXPONENCIALES Y SU REPRESENTACION GRAFICA
000000001 250   L $$a1 ED
000000001 260   L $$aMADRID:$$b JUNTA DE ENERGIA NUCLEAR,$$c1983
000000001 300   L $$a58 P. + 5 REFERENCIAS BIBLIOGR., 1 H. DE FICHAS CON REFERENCIA BIBLIOGRAFICA Y RESUMEN DEL INFORME
000000001 340   L $$aPAPEL
