Dear RubiC,

My actual data are as below. I simplified them my previous messages to be understood but a little bit confused. Sorry for that
Code:
2015.314.07.57.59.3200.GR.GAZ.BHE.D.DAT
2015.314.07.57.59.3200.GR.GAZ.BHN.D.DAT
2015.314.07.58.00.6600.GR.GAZ.BHZ.D.DAT

2015.314.07.58.00.1000.GR.SVRC.BHE.D.DAT
2015.314.07.58.01.1200.GR.SVRC.BHN.D.DAT
2015.314.07.58.01.7400.GR.SVRC.BHZ.D.DAT

2015.314.08.02.26.0000.GR.MALT.HHE.D.DAT
2015.314.08.02.38.0000.GR.MALT.HHN.D.DAT
2015.314.08.02.59.4000.GR.MALT.HHZ.D.DAT

2015.314.08.05.24.0000.GR.GMLD.HNZ.D.DAT
2015.314.08.05.26.0000.GR.GMLD.HNE.D.DAT
2015.314.08.05.26.0000.GR.GMLD.HNN.D.DAT
2015.314.08.05.29.0000.GR.GMLD.HNZ.D.DAT
2015.314.08.05.31.0000.GR.GMLD.HNN.D.DAT
2015.314.08.05.34.0000.GR.GMLD.HNZ.D.DAT
2015.314.08.05.36.0000.GR.GMLD.HNE.D.DAT
2015.314.08.05.36.0000.GR.GMLD.HNN.D.DAT
2015.314.08.05.39.0000.GR.GMLD.HNZ.D.DAT
2015.314.08.05.41.0000.GR.GMLD.HNN.D.DAT

In here, the numbers represent to date,time. GR is network code. GAZ, SVRC, MALT and GMLD are station names. BH? or HH? are components. The rest is not important.

As you see, in the first three group, each file (BHE, BHE, BHZ or HHE,HHN,HHZ) contains full data. They are ok for me. But last group contains more than one HHE, HHN and HHZ files. Those are parted by conversion program.

My aim is to find more than one XXXX.HHE (or XXXX.BHE), XXXX.HHN (or XXXX.BHN) and XXXX.HHZ (or XXXX.BHZ) files and list them in a file.

If your flavor of Unix supports uniq with -D option, this should meet your requirement of listing all duplicate file names ignoring the first 26 characters.

Code:
ls | sort -t'.' -k8,9 | uniq -s 26 -D
