Find in file. Does this exist under UNIX?
Hello,
I have the following problem. I know there is a file somewhere on a UNIX machine that contains a string, but I don't know where.
With the "grep" command, I can look into a file but only if I'm located in the correct directory.
With the "find" command, I can search across directories but I cannot specify to search within the files for a certain string.
Does there exist a standard UNIX command for looking for a text within a file without knowing the directory in which the file is located?
Thanks
Dominique

mcopy(1) General Commands Manual mcopy(1)
NAME
mcopy - mtools utility to copy DOS files to and from a UNIX operating system
SYNOPSIS
mcopy [-mntv] sourcefile targetfile
mcopy [-mntv] sourcefile [sourcefiles...] targetdirectory
OPTIONS
Preserves the file modification time. Specifies that a warning is not issued when an existing file is specified as the target file. If
this option is not specified, the mcopy command verifies whether or not to overwrite an existing file. Specifies a text file transfer.
Line terminators are converted to the appropriate format. Specifies verbose mode. The new file name is displayed if the name supplied is
invalid.
DESCRIPTION
The mcopy command copies the specified file to the named file, or copies multiple files to the named directory. The specified files or
directories can be either DOS or UNIX files.
If the file is a text file line terminators are converted to the appropriate format.
Using a drive letter designation on the DOS files such as 'a:' determines the direction of the transfer. A missing drive designation indi-
cates a UNIX file whose path starts in the current directory.
DOS subdirectory names that contain the '/' or '' separator are supported. If you use the '' separator or wildcards, you must enclose
file names in quotes to protect them from the shell.
The mcd command can be used to establish the device and the current working directory (relative to DOS), otherwise the default is A:.
Not all UNIX file names are supported in the DOS world. The mcopy command may have to change UNIX names to fit the DOS file name conven-
tions. The following table shows some examples of file name conversions:
-----------------------------------------------
UNIX name DOS name Reason for the change
-----------------------------------------------
thisisatest THISISAT file name too long
file.stuff FILE.STU extension too long
prn.txt XRN.TXT PRN is a device name
.abc X.ABC null file name
hot+cold HOTXCOLD illegal character
-----------------------------------------------
RESTRICTIONS
The following restrictions exist: Omitting the destination directory is not supported. Using the plus (+) operator is not supported.
Using a drive letter designation on DOS files is required with this command only, not with other mtools.
EXIT STATUS
The following exit values are returned: Success. Failure.
ENVIRONMENT VARIABLES
The following environment variables affect the execution of mcopy: If set, this variable names the file that contains the name of the cur-
rent mtools working directory as established by the mcd command. If this variable is not set, the file $HOME/.mcwd is used.
FILES
Contains the name of the current mtools working directory as established by the mcd command. If this file does not exist, the default
mtools working directory is A:. Executable file
