In the current directory , I have seven files .
But when I use the following command , it lists eight files ( 7 files + file_list.xtx)
Does the tee command create the file_list.xtx file first and then executes the ls -1 command ? My understanding was: 1. First the ls -1 command will get executed listing the 7 files
2. Entries of all th seven files will be written in a new file created by the tee command (file_list.xtx)
3. The output of ls -1 command ( entries of 7 files only ) will ve passed to the while loop for further processing
Hi,
I am using /bin/sh. I want to display the stdout and stderr on the terminal as well as save it in a file, so I'm using this command.
gmake all 2>&1 | tee log
But even if gmake fails, it's always giving 0 as exit status, i suppose because of tee.
# false 2>&1 | tee Log
# echo $?

shar
SHAR(1) BSD General Commands Manual SHAR(1)NAME
shar -- create a shell archive of files
SYNOPSIS
shar file ...
DESCRIPTION
shar writes an sh(1) shell script to the standard output which will recreate the file hierarchy specified by the command line operands.
Directories will be recreated and must be specified before the files they contain (the find(1) utility does this correctly).
shar is normally used for distributing files by ftp(1) or mail(1).
SEE ALSO compress(1), mail(1), tar(1), uuencode(1)BUGS
shar makes no provisions for special types of files or files containing magic characters.
EXAMPLES
To create a shell archive of the program ls(1) and mail it to Rick:
cd ls
shar `find . -print` | mail -s "ls source" rick
To recreate the program directory:
mkdir ls
cd ls
...
<delete header lines and examine mailed archive>
...
sh archive
HISTORY
The shar command appears in 4.4BSD.
SECURITY CONSIDERATIONS
It is easy to insert trojan horses into shar files. It is strongly recommended that all shell archive files be examined before running them
through sh(1). Archives produced using this implementation of shar may be easily examined with the command:
egrep -v '^[X#]' shar.file
