Looks like it. :-) > Can anybody reproduce this behaviour? Yes: % jobs [1] Suspended gv aaaa.ps [2] Suspended xpdf /tmp/w3dzz-antenna-iss-1-31.pdf [3] - Suspended xpdf /tmp/robe.pdf [4] + Suspended xpdf /tmp/anwenderaspekte_svm_3.3.pdf % fg 3 xpdf /tmp/anwenderaspekte_svm_3.3.pdf But using the correct syntax, this happens (as expected): % fg %3 xpdf /tmp/robe.pdf Explanation from "man csh": There are several ways to refer to jobs in the shell. The character `%' introduces a job name. If you wish to refer to job number 1, you can name it as `%1'. Just naming a job brings it to the foreground; thus `%1' is a synonym for `fg %1', bringing job 1 back into the fore- ground. Similarly, saying `%1 &' resumes job 1 in the background, just like `bg %1'. A job can also be named by an unambiguous prefix of the string typed in to start it: `%ex' would normally restart a suspended ex(1) job, if there were only one suspended job whose name began with the string `ex'. It is also possible to say `%?string' to specify a job whose text contains string, if there is only one such job. [...] fg [%job ...] Brings the specified jobs (or, without arguments, the current job) into the foreground, continuing each if it is stopped. job may be a number, a string, `', `%', `+' or `-' as described under Jobs. See also the run-fg-editor editor command. So the command > fg %3 ^ will probably do what you want. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
