Cygwin allows you to use either CR/LF or LF line endings - it's a registry key setting, IIRC.

Try running dos2unix on your shell script to change CR/LF to LF.

Why sed and not cat?

I suppose you could do something like sed : file1 file2

The OP said Flash. Other options are PXE booting + NFS. Truly diskless workstations are out there.

Your $DISPLAY variable is not getting set for some reason.

Is the output on stdout and not stderr (fd2)?

You can see what it is at:
Home -> Menu -> Settings -> (page 2) -> Device Email

You can change the address online, and set up allowed source email addresses. I don't remember what the default...

What OS/utility version are you using?

On a GNU/Linux system, I can run this:

# lsof -Pni4 | grep -c ":22 "
2
#


In my case, I'm just counting ssh sessions. You can change ":22 " to...

I like scripting in bash. It's close to POSIX, and a contender for ksh, which I haven't used a lot in the last few years, since I work almost exclusively on GNU/Linux kit.

My gripes about bash are...

Easy enough.

#! /bin/bash

filename=my.test.file.flag
if [[ "$filename" =~ "flag" ]]; then
printf '%s\n' "Matched flag"
fi

OK, how about:

#! /usr/bin/ksh

for file in *; do
if [[ "${file:(-4)}" == "flag" ]]; then
# Do some processing here. Maybe:
/bin/mv "$file" /tmp/
else
# Do something else. Maybe...

You need to be very clear here.

What do you mean by "suspending" based on a file? What exactly do you want to do?

I'm not sure I understand completely.

Do you want the filename minus ".flag"? If so:

#! /usr/bin/ksh

testfile=my.test.file.flag
printf '%s\n' "${testfile%.flag}"

Look again at fpmurphy's suggestion. The ssh daemon attempts to be secure, and doesn't always like world-readable files, especially files that shouldn't be, like ~/.ssh/authorized_keys2 or...

If you specify . ./file.ksh, it's like running the contents of that file in your current shell. It's a bit smarter than this, but think of it running:
while read line; do "$line"; done <file.ksh...

OK, here's try #2:

#! /bin/bash

for file in /logs/logfile.*; do
while read ip; do
if [[ "${file#${file%??}}" == ".Z" ]]; then
# This is a compressed file - it ends with .Z - use zgrep...

Please use [code] tags around your output to help line it up properly.

I'm not sure what you mean - is it really full, or are you out of inodes (two different issues)? If it says it's full, and...

My first guess would be:

#! /bin/bash

logfile=/path/to/logfile
while read ip; do
zgrep "$ip" $logfile > output_logfile_${ip}
done <iplist


It could be done more elegantly, and maybe...

I'm rather fond of pdsh, which includes pdcp for copying files to/from a large number of nodes.

What is your input filename and expected output filename set?

As a proof of concept, assume I put your example in "tmp.in" and ran this script:

#! /bin/bash

declare i=1
while read line; do ...

More importantly, what 'tar' do you have? For example, nothing is stopping you from running GNU tar on a Solaris-kernel system. Nothing prevents you from writing or modifying your own tar command and...

Assuming this is a Linux kernel, have you tried looking in the /sys filesystem?

It's all driver and device specific, so I can't give you any better answers in this case off-hand, but here's some...

You need to be very specific.

If you're launching an ssh client, see your client's documentation for it's support for ANSI color codes, or set the defaults in it's preferences.

What client...

I'd buy Bill Joy a beer for vi, but punch him halfway through the round for NFS and csh.

I guess we shouldn't blame him completely, though. NFS and csh were good for their time - it's those lousy...

This works in bash:

echo ${PWD##*/}


[Edit: Derp - I somehow missed everyone else's replies. Sorry for the repeat.]

The ext4 filesystem supports a 'relatime' option to avoid those extraneous small-I/O writes every time you touch a file. This isn't usually a big deal on single-spindle disks, but if you run a large...
