NAME

MDK::Common::File - miscellaneous file/filename manipulation functions

SYNOPSIS

use MDK::Common::File qw(:all);

EXPORTS

dirname(FILENAME)

basename(FILENAME)

returns the dirname/basename of the file name

cat_(FILES)

returns the files contents: in scalar context it returns a single string, in array context it returns the lines.

If no file is found, undef is returned

cat_or_die(FILENAME)

same as cat_ but dies when something goes wrong

cat_utf8(FILES)

same as C(<cat_>) but reads utf8 encoded strings

cat_utf8_or_die(FILES)

same as C(<cat_or_die>) but reads utf8 encoded strings

cat__(FILEHANDLE REF)

returns the file content: in scalar context it returns a single string, in array context it returns the lines

output(FILENAME, LIST)

creates a file and outputs the list (if the file exists, it is clobbered)

output_utf8(FILENAME, LIST)

same as C(<output>) but writes utf8 encoded strings

secured_output(FILENAME, LIST)

likes output() but prevents insecured usage (it dies if somebody try to exploit the race window between unlink() and creat())

append_to_file(FILENAME, LIST)

add the LIST at the end of the file

output_p(FILENAME, LIST)

just like output but creates directories if needed

output_with_perm(FILENAME, PERMISSION, LIST)

same as output_p but sets FILENAME permission to PERMISSION (using chmod)

mkdir_p(DIRNAME)

creates the directory (make parent directories as needed)

rm_rf(FILES)

remove the files (including sub-directories)

cp_f(FILES, DEST)

just like "cp -f"

cp_af(FILES, DEST)

just like "cp -af"

cp_afx(FILES, DEST)

just like "cp -afx"

linkf(SOURCE, DESTINATION)

symlinkf(SOURCE, DESTINATION)

renamef(SOURCE, DESTINATION)

same as link/symlink/rename but removes the destination file first

touch(FILENAME)

ensure the file exists, set the modification time to current time

all(DIRNAME)

returns all the file in directory (except "." and "..")

all_files_rec(DIRNAME)

returns all the files in directory and the sub-directories (except "." and "..")

glob_(STRING)

simple version of glob: doesn't handle wildcards in directory (eg: */foo.c), nor special constructs (eg: [0-9] or {a,b})

substInFile { CODE } FILENAME

executes the code for each line of the file. You can know the end of the file is reached using eof

expand_symlinks(FILENAME)

expand the symlinks in the absolute filename: expand_symlinks("/etc/X11/X") gives "/usr/bin/Xorg"

openFileMaybeCompressed(FILENAME)

opens the file and returns the file handle. If the file is not found, tries to gunzip the file + .gz

catMaybeCompressed(FILENAME)

cat_ alike. If the file is not found, tries to gunzip the file + .gz
