Mojibake means "character transformation" in Japanese. Causes[ edit ] To correctly reproduce the original text that was encoded, the correspondence between the encoded data and the notion of its encoding must be preserved.
Print out the portion of the pattern space up to the first newline. H Append a newline to the contents of the hold space, and then append the contents of the pattern space to that of the hold space.
G Append a newline to the contents of the pattern space, and then append the contents of the hold space to that of the pattern space. Extended CommandsPrevious: Other CommandsUp: But occasionally one is committed to sticking with sed, and these commands can enable one to write quite convoluted scripts.
In all other respects, a no-op. The label may be omitted, in which case the next cycle is started. Multiple commands syntaxPrevious: Programming CommandsUp: They allow you to check for GNU sed extensions or to do tasks that are required quite often, yet are unsupported by standard seds.
Without parameters, the e command executes the command that is found in pattern space and replaces the pattern space with the output; a trailing newline is suppressed. If a parameter is specified, instead, the e command interprets it as a command and sends its output to the output stream.
The command can run across multiple lines, all but the last ending with a back-slash. In both cases, the results are undefined if the command to be executed contains a NUL character. Note that, unlike the r command, the output of the command will be printed immediately; the r command instead delays the output to the end of the current cycle.
F Print out the file name of the current input file with a trailing newline. Q [exit-code] This command accepts only one address.
This command is the same as q, but will not print the contents of pattern space. Like q, it provides the ability to return an exit code to the caller.
This command can be useful because the only alternative ways to accomplish this apparently trivial function are to use the -n option which can unnecessarily complicate your script or resorting to the following snippet, which wastes time by reading the whole file without any visible effect: Note that if filename cannot be read, or if its end is reached, no line is appended, without any error indication.
T label Branch to label only if there have been no successful substitutions since the last input line was read or conditional branch was taken.
In addition, you can specify the version of sed that your script requires, such as 4. The default is 4. W filename Write to the given filename the portion of the pattern space up to the first newline. Everything said under the w command about file handling holds here too.A great display resource for children to refer to when writing independently.
Banner is larger than usual - split over 4xA4 sheets, to allow larger display letters. This is a great idea!
