如何删除记录中的某些模式？

Question

我有一个文件，其中有数百个以下列格式记录：

20150416110321|21,VPLA,91974737XXX5|91974737XXX5,404192086271201|404192086271201,SAI-IMEISV,gsn65.xxxxx.com,gsn65.xxxxx.com;1429148977;301814701;11276100,100.XX.199.250|100.XX.199.XXX|,1,SAIOLU-Location,SAIOLU-LG,2,internet|internet,,SAIOLU-SGSNIP,6,AL,AL_F_1_25G40K_2_25G20K_28|KL_BASIC,,UNKNOWN,SAIOLU-MK,UNKNOWN,SAIOLU-MBRUL,SAIOLU-MBRDL,,,,SAI-IMEI,,,,

我只想在字段/列1-8中仅取出管道分隔数据的第一部分。我怎么能用awk / sed做到这一点？

例如：

20150416110321,VPLA,91974737XXX5,404192086271201,SAI-IMEISV,gsn65.xxxxx.com;1429148977;301814701;11276100,100.XX.199.250,1,SAIOLU-Location,SAIOLU-LG,2,internet|internet,,SAIOLU-SGSNIP,6,AL,AL_F_1_25G40K_2_25G20K_28|KL_BASIC,,UNKNOWN,SAIOLU-MK,UNKNOWN,SAIOLU-MBRUL,SAIOLU-MBRDL,,,,SAI-IMEI,,,,
