I want a shell script which does:
-> search all .mov files in a drive (say e: drive) which are above 800 mb of size
-> Delete the searched .mov files which are above 800mb
Thanks,
Manoj
From the man page of find:
-name pattern
Base of file name (the path with the leading directories
removed) matches shell pattern pattern. The metacharacters
(`*', `?', and `[]') match a `.' at the start of the base name
(this is a change in findutils-4.2.2; see section STANDARDS CON-
FORMANCE below). To ignore a directory and the files under it,
use -prune; see an example in the description of -wholename.
Braces are not recognised as being special, despite the fact
that some shells including Bash imbue braces with a special
meaning in shell patterns. The filename matching is performed
with the use of the fnmatch(3) library function. Don't forget
to enclose the pattern in quotes in order to protect it from
expansion by the shell.
-size n[cwbkMG]
File uses n units of space. The following suffixes can be used:
`b' for 512-byte blocks (this is the default if no suffix is
used)
`c' for bytes
`w' for two-byte words
`k' for Kilobytes (units of 1024 bytes)
`M' for Megabytes (units of 1048576 bytes)
`G' for Gigabytes (units of 1073741824 bytes)
The size does not count indirect blocks, but it does count
blocks in sparse files that are not actually allocated. Bear in
mind that the `%k' and `%b' format specifiers of -printf handle
sparse files differently. The `b' suffix always denotes
512-byte blocks and never 1 Kilobyte blocks, which is different
to the behaviour of -ls.
-exec command ;
Execute command; true if 0 status is returned. All following
arguments to find are taken to be arguments to the command until
an argument consisting of `;' is encountered. The string `{}'
is replaced by the current file name being processed everywhere
it occurs in the arguments to the command, not just in arguments
where it is alone, as in some versions of find. Both of these
constructions might need to be escaped (with a `\') or quoted to
protect them from expansion by the shell. See the EXAMPLES sec-
tion for examples of the use of the `-exec' option. The speci-
fied command is run once for each matched file. The command is
executed in the starting directory. There are unavoidable
security problems surrounding use of the -exec option; you
should use the -execdir option instead.
-exec command {} +
This variant of the -exec option runs the specified command on
the selected files, but the command line is built by appending
each selected file name at the end; the total number of invoca-
tions of the command will be much less than the number of
matched files. The command line is built in much the same way
that xargs builds its command lines. Only one instance of '{}'
is allowed within the command. The command is executed in the
starting directory.
Combining that:
find /path/to/search -name '*.mov' -size +800M -exec rm {} \;
e: is a MSDOS notation not unix.
What Operating System are you running?
If it is referrring to Unix FS , make use of the -xdev option.
find dir_name -name "*.mov" -type f -xdev -size +800m -exec rm -f {} \;
when i executed dennis command, i got this message in linux.
find: warning: you have specified the -xdev option after a non-option argument -name, but options are not positional (-xdev affects tests specified before it as well as those specified after it). Please specify options before other arguments.
However i have not yet tried pludi's command in windows. I will reply once i do it in windows.
