. You can also use the find command to find a file and then carry out a command on that file. To do this use the command: find pathname -name filename -print -exec command {}\; . To be prompted for confirmation before the command is executed use the command: find pathname -name filename -print -ok command {}\; . The command must be followed by a \ (backslash) and a ; (semi-colon). The {} (pair of braces) substitute the pathname of the file that is found as an argument to the command. Examples .

Jupiter's volcano-pocked moon Io has been found by NASA's Galileo spacecraft to have a giant iron core that takes up half its diameter, scientists report in today's issue of Science magazine. The spacecraft also has detected a large "hole" in Jupiter's magnetic field near Io, leading to speculation about whether Io possesses its own magnetic field. ... Galileo scientists also are trying to determine the cause of the hole they found in Jupiter's magnetic field when the spacecraft was closest to Io. ...

The preliminary ALFA pulsar surveys started on August 1st, 2004. In the first day of observations, a new 67.8-ms pulsar, PSR J1928+1746, was discovered: this was the first new pulsar found with ALFA. ... Strangely, the pulsar could not be detected in a 430-MHz observation. This pulsar's apparently unusual spectrum might not be so unusual: 1400-MHz surveys are biased towards finding this kind of object, but the pulsars found in these surveys were not consistently observed at higher frequencies. ...
