Argument list too long

해당 디렉토리로 가서 아래 스크립트 실행

for file in $(ls)
do
    rm -fv $file
done


안써먹으니 이 간단한것도 기억에서 잊혀진다.


# find ./ -name "*.log" -print0 
./1.log./2.log

 

# find ./ -name "*.log" -print0 | xargs -0 rm -f
# ls

다 지워 졌음.

 

 

find 옵션

-print0
True; print the full file name on the standard output, followed by a null
character (instead of the newline character that '-print' uses). This
allows file names that contain newlines or other types of white space to be
correctly interpreted by programs that process the find output. This option
corresponds to the '-0' option of xargs.

 

 

xargs 옵션

--null, -0

Input items are terminated by a null character instead of by whitespace, and
the quotes and backslash are not special (every character is taken liter-
ally). Disables the end of file string, which is treated like any other
argument. Useful when input items might contain white space, quote marks,
or backslashes. The GNU find -print0 option produces input suitable for
this mode.

find / -type f \( -perm -2 -o -perm -20 \) -exec ls -lg {} \;


find 옵션중.

-perm mode
File's permission bits are exactly mode (octal or symbolic). Since an exact match is
required, if you want to use this form for symbolic modes, you may have to specify a rather
complex mode string. For example '-perm g=w' will only match files which have mode 0020
(that is, ones for which group write permission is the only permission set). It is more
likely that you will want to use the '/' or '-' forms, for example '-perm -g=w', which
matches any file with group write permission. See the EXAMPLES section for some illustra-
tive examples.

 

ls 옵션중

       -l     use a long listing format

       -g     like -l, but do not list owner
