<p>
|
||
Both commands show the content of one or more files and it’s possible to do a research with
|
||
particular flags, but the “less” one allows us to go also backwards while reading the text
|
||
of a file.<br>
|
||
More is quite old, less is more recent and powerful.<br>
|
||
|
||
General syntax for both is:
|
||
</p>
|
||
|
||
<pre>
|
||
less [flags] path/name-file.*
|
||
more [flags] path/name-file.*
|
||
</pre>
|
||
|
||
<p>
|
||
The command <code>less</code> provides some useful commands to navigate and modify the file content.
|
||
Commands does not include flags, which are included under <i>Options</i>.
