bash question

[Eric Vogel]

I am using bash shell and the one thing that I can't seem to find is the
'more' command.  I can't believe that it is not implemented somewhere
since with the exception of 'ls' it is my most used command.

Erich Vogel

Sorry, wrong answer.  You're just printing out the first count again.
The second count is lost, but happens to be 3 also.  Add couple of lines
to the file to see:
$ ./tscript.sh
item 1
item 2
item 3
Processed 3 items
Read item 1 1
Read item 2 2
Read item 3 3
Read item 4 4
Read item 5 5
Processed 3 items

The following version works:
#!/bin/bash

i=0
for x in 1 2 3; do
  let i=i+1
  echo "item $x"
done

echo "Processed $i items"

i=0
cat > /tmp/file <<END
item 1
item 2
item 3
item 4
item 5
END

while read item; do
  let i=i+1 ;
  echo "Read $item $i" ;
done < /tmp/file  #NOTE this placement of redirection
####################################### now run it
$ ./tscript.sh
item 1
item 2
item 3
Processed 3 items
Read item 1 1
Read item 2 2
Read item 3 3
Read item 4 4
Read item 5 5
Processed 5 items

Re: bash question

[Mark Blackburn]

You asked this in the wrong place btw, (I think its a bash specific
questing) but here goes anyways:
#!/bin/bash

i=0
for x in 1 2 3; do
  let i=i+1
  echo "item $x"
done

echo "Processed $i items"

cat > /tmp/file <<END
item 1
item 2
item 3
END

cat /tmp/file | { export i=0; while read item; do \
  let i=i+1 ; \
  echo "Read $item $i" ; \
done }

echo "Processed $i items"

rm -f /tmp/file

output is:
item 1
item 2
item 3
Processed 3 items
Read item 1 1
Read item 2 2
Read item 3 3
Processed 3 items

bash question

[Andrew DeFaria]

I may have asked this before but I'd really like to understand this and 
get a fix for it. Given the following script:

#!/bin/bash

declare -i i=0

for x in 1 2 3; do
  let i=i+1
  echo "item $x"
done

echo "Processed $i items"

cat > /tmp/file <<END
item 1
item 2
item 3
END

declare -i i=0

cat /tmp/file | while read item; do
  let i=i+1
  echo "Read $item"
done

echo "Processed $i items"

rm -f /tmp/file

I get the following output:

$ test.sh
item 1
item 2
item 3
Processed 3 items
Read item 1
Read item 2
Read item 3
Processed 0 items

The quesiton is why is the integer "i" reporting 0 items processed for 
the second loop? I know that it has to do with the fact that a pipe is 
involved. However, how can I code this so that "i" survives?

BASH question

[Pytel, Diane]

Help!
I'm a first time user of cygwin stuff and trying to install it on a PC
with
Windows 95 OS.  When I try to run a small C program I keep getting the
message:
BASH.EXE: a.exe: cmd not found.  Details of installation are below

I wrote a small C program from class and got an a.exe file.  I guess I
don't understand 2 things:
1)  why I'm getting a .exe file from gcc.  This means I'm operating in
DOS.  I thought choosing UNIX would override that but I guess I'm too
dumb about dos and such.
2)  why I'm getting the error msg BASH.EXE: a.exe: cmd not found

Thank you.
Diane Pytel

To set up I did the following:
Clicked the install cygwin now and downloaded set up.
double clicked to run set up
hit next
hit install from Internet
local package dir is C:\\Windows
direct connect
download site ftp.freesoftware.com
under select, all of the ones that I think I wanted were listed so I did
nothing even though it said select (clicking on them gave a 'skip' so
this page was left alone)
It downloaded everything and gave me an installation complete.

OH yeah, somewhre in there I chose, UNIX and for me only.

Yes, create an env var named HOME pointing to wherever you want -
preferrably to your real home directory.

yes, if your $HOME environment variable is set to your user's home dir it will
create the .bash_history file there and not in your root dir.

[Eric Vogel]

I installed your gnu-win32 developement platform and I'm using the
bash shell.  Everything seems to be included except the 'more'
command which I use all the time.  I have looked for another command
to replace it but I can't seem to find one.

I may have sent this question a few days ago, but my mail system
wasn't set up correctly, so the reply may have bounced back.

Let me first point you to some important documents:

Read the README.txt and faq.txt file located at 
ftp://ftp.cygnus.com/pub/gnu-win32/latest/ .

Then take a look at the http://www.cygnus.com/ml/gnu-win32 web page.  
This is the mail list archive and you will be able to find the answers 
to many questions.

Goodluck,

Wei Ku answered your question, but here's my 2 cents worth:

It works like unix.  Unless you have a "." in your path, you have to
execute files in the current dir like this:

./runthis

If the file is hidden (i.e., .login; .profile) then you do this:

./.profile
./.login

Re: Bash Question.

[Wei Ku]

1. There should not be any problem for bash to show the current working
directory. pwd always works.
2. to all the files in the current directory to be run, try to add . ( dot )
in PATH
ex: export PATH=.:/bin:$HOME/bin

Sincerely,
Wei Ku

Bash Question.

[Bardley09]

This is probably elementary...but.  Bash doesn't recognize the current
directory (i.e. pwd) and won't execute commands there unless it's
in the path.  There must be a way to make it do that.  I confess I have not
yet scoured the mail archives on this matter.
