Specifically what is the purpose of sed?
What is f?
Why is the 'cp f $phonefile' line needed when the script ‘goes live'?
Why might that two commands following sed be commented out at the present time ( i.e., during development)?

I am using this line of perl code to change the file format and remove ^M at the end of each line in files:
perl -i -pe's/\r$//;' <name of file here>
Can you explain to me what this code does, and translate it into bash/awk/sed? (2 Replies)
Hi,
I saw this. But I don't know why we need this?
ls mydir > foo.txt ## I know what this will do, it will take the results and write to the file called foo.txt
ls mydir > foo.txt 2>&1 ## Don't know why we need 2>&1
Thanks. (2 Replies)
Please explain grep -A 999999. I've seen this before, it always seems to be with six 9's as well. See an example below.

I have a requirement to remove all non-ascii characters from a fixed length file. I used the below command which is removing special characters but somehow the total record length is being truncated to one space less. If it is a multi-byte string then many characters at the end are being truncated.... (8 Replies)

whereis
whereis(1B) SunOS/BSD Compatibility Package Commands whereis(1B)NAME
whereis - locate the binary, source, and manual page files for a command
SYNOPSIS
/usr/ucb/whereis [-bmsu] [ -BMS directory... -f] filename...
DESCRIPTION
The whereis utility locates source/binary and manuals sections for specified files. The supplied names are first stripped of leading path-
name components and any (single) trailing extension of the form .ext, for example, .c. Prefixes of s. resulting from use of source code
control are also dealt with. whereis then attempts to locate the desired program in a list of standard places:
etc
/sbin
/usr/bin
/usr/ccs/bin
/usr/ccs/lib
/usr/lang
/usr/lbin
/usr/lib
/usr/sbin
/usr/ucb
/usr/ucblib
/usr/ucbinclude
/usr/games
/usr/local
/usr/local/bin
/usr/new
/usr/old
/usr/hosts
/usr/include
/usr/etc
OPTIONS
The following options are supported:
-b Searches only for binaries.
-B Changes or otherwise limits the places where whereis searches for binaries.
-f Terminates the last directory list and signals the start of file names, and must be used when any of the -B, -M, or -S options are
used.
-m Searches only for manual sections.
-M Changes or otherwise limits the places where whereis searches for manual sections.
-s Searches only for sources.
-S Changes or otherwise limit the places where whereis searches for sources.
-u Searches for unusual entries. A file is said to be unusual if it does not have one entry of each requested type. Thus
`whereis -m-u *' asks for those files in the current directory which have no documentation.
EXAMPLES
Example 1: Finding files
Find all files in /usr/bin which are not documented in /usr/share/man/man1 with source in /usr/src/cmd:
example% cd /usr/ucb
example% whereis -u -M /usr/share/man/man1 -S /usr/src/cmd -f *
FILES
/usr/src/*
/usr/{doc,man}/*
/etc, /usr/{lib,bin,ucb,old,new,local}
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWscpu |
+-----------------------------+-----------------------------+
SEE ALSO chdir(2), attributes(5)BUGS
Since whereis uses chdir(2) to run faster, pathnames given with the -M, -S, or -B must be full; that is, they must begin with a `/'.
