Most people use the job number to refer to a job, because one number is easy to remember. However, jobs can be referred to in a number of other ways: by process id, current/previous job, or all or part of a job name. If we had these jobs: $ jobs l [3] + 466 Stopped split ?000 hugefile [2] ?465 Running find / name print & [1] 463 Running sleep 25 & then the split job could be referred to as %3, %+, %%, 466, %split, or %?sp, the find job could be referred to as %2, %?/span>, 465, %find, or %?f, and the sleep could be referred to as %1, 463, %sleep, or %?sl. Table 5.2. Job Names %n | job n | %+, %% | current job | %?/span> | previous job | %string | job whose name begins with string | %?string | job that matches part or all of string | |
