1496 | * |
1497 | * 1) "compatible" -- this format is compatible with the original lscpu(1) | |
1498 | * output and it contains fixed set of the columns. The CACHE columns are at | |
1499 | * the end of the line and the CACHE is not printed if the number of the caches | |
1500 | * is zero. The CACHE columns are separated by two commas, for example: | |
1501 | * | |
1502 | * $ lscpu --parse | |
1503 | * # CPU,Core,Socket,Node,,L1d,L1i,L2 | |
1504 | * 0,0,0,0,,0,0,0 | |
1505 | * 1,1,0,0,,1,1,0 | |
1506 | * | |
1507 | * 2) "user defined output" -- this format prints always all columns without | |
1508 | * special prefix for CACHE column. If there are not CACHEs then the column is | |
1509 | * empty and the header "Cache" is printed rather than a real name of the cache. | |
1510 | * The CACHE columns are separated by ':'. | |
1511 | * | |
1512 | * $ lscpu --parse=CPU,CORE,SOCKET,NODE,CACHE | |
1513 | * # CPU,Core,Socket,Node,L1d:L1i:L2 | |
1514 | * 0,0,0,0,0:0:0 | |
