问题
I'd like to find human-readable files on my linux machine without a file extension constraint. Those files should be of human sensing files like text, configuration, html, source-code etc. files. Could you suggest a way to filter and locate.
回答1:
find and file are your friends here:
find /dir/to/search -type f -exec sh -c 'file -b {} | grep text &>/dev/null' \; -print
this will find any files ( NOTE: it will not find symlinks directories sockets etc only regular files ) in /dir/to/search and run sh -c 'file -b {} | grep text &>/dev/null' \; which looks at the type of file and looks for text in the description. if this returns true ( ie text is in the line) then it prints the filename.
NOTE: using the -b flag to filemeans that the filename is not printed and therefore cannot create any issues with the grep. eg without the -b flag the binary file gettext would erroneously be detected as a textfile.
eg
root@osdevel-pete# find /bin -exec sh -c 'file -b {} | grep text &>/dev/null' \; -print
/bin/gunzip
/bin/svnshell.sh
/bin/unicode_stop
/bin/unicode_start
/bin/zcat
/bin/redhat_lsb_init
root@osdevel-pete# find /bin -type f -name *text*
/bin/gettext
EDIT:
If you want to look in compressed files use the --uncompress flag to file. for more info and flags to file see man file

How about
find /dir/to/search -type f | xargs file | grep text
find
will give you a list of files.
xargs file
will run the file
command on each of the lines from the piped input.

i use
file directory/to/search/*
For example to find only human readable files in a directory called home use:
file home/*
and the readable file will have a format such as ASCII text
