Copy stdout/stderr to a file

I want to run an executable and display its contents. Sometimes the contents include the word "ERROR". I want to be able to run the program, show all the contents, then see if the word Error is there. I could do program > somefile 2>&1 cat file if [ -z `grep ERROR somefile` ] ; then echo "An error occurred" exit 1 fi but that would not show the contents until after I'd run the program. I'd like to show all the contents as the prgram runs, then afterwards grep for the word ERROR. I thought I could do this with "tee", but I don't seem to be getting anywhere. Any sugge

Equally Tab Spaced Columns Through sed

Hi! I have a somehow long file (almost 3000 lines) and I would like to space each column using tabs, but I can't figure how to do that through sed. Here you are an excerpt from the data I have: Madagascar 1995 51.6 Malawi 1995 54.7 Saint_Vincent_and_the_Grenadines 2010 66.9 Samoa 2010 60.4 S=E3o_Tom=E9_and_Pr=EDncipe 2010 48.8 Saudi_Arabia 2010 64.1 I would like that each line could be as follows: Madagascar 1995 51.6 Malawi 1995 54.7 Saint_Vincent_and_the_Grenadines 2010 66.9 Samoa 2010 60.4 S=E3o_Tom=E9_and_Pr=EDncipe 2010 48.8 Saudi_Arabia 2010 64.1 As

delete mach and next two words in text file

Hello, I have been trying to do this for a while now, still with no success. Basically I have a file with several numbers all in one line separated by a space. Every three numbers are values for one item. When the item does not exist anymore I have to delete the entries in the file. This means that if item 2 is gone, for example, values 3 4 5 have to be deleted (item 1 would be values 0 1 2). File example: 12 25 33 0 1 5222 89 90 3 67 67 0 12 56 11 First item = 12 25 33 (12 being in position 0 and 25 being in position 1 in the file and so on ...) Second item = 0 1 5222 and

setting dircolors--clarification

Alright having played with LS_COLORS a bit and figuring out what is going on, I can now better describe exactly what I am looking for. If you look at dircolors, you discover there are 8 foreground colors and 8 background colors you can set the font to. Furthermore the eight colors are preset and basic. Shoot the background yellow isn't even yellow on my system it's orange. Now what I would really like is a way to get more colors ( though eight might just be enough ).; But also I want to chose the colors that I can chose in my scheme. In emacs you get all sorts of colors lig

Weirdest shell behavior ever...

Okay, weirdest I've seen. There's a hunk of shell code I use to generate some large hunks of source code. The basic logic looks like this: exec 5>wrapfuncs.c for i in big_list do cat >&5 <<EOF int $i(void) { EOF cat >&5 <<EOF return 3; } EOF cat >&5 <<EOF int dummy_$i(void) { return 4; } EOF done (The contents are actually much more complicated.) Out of about fifty thousand runs, we've had two fail, both on the same host, both on the same day. The failure is that the entire file comes out fine, except that ONE instance (out of dozens) in the fi

GNU sed regex assistance needed

Hi all, I'm working on a large wiki migration; there's one special case pattern the supplied migration script isn't accounting for, and I'm apparently far less skilled with sed than I originally hoped -- the correct command has been eluding me for an hour now. I'm trying to use GNU sed to change patterns like the following from double square brackets to double angle brackets: [[Include(SomeWiki/PageName)]] into: <<Include(SomeWiki/PageName)>> A valid pattern inside the parentheses contains [A-Za-z0-9_.-/] I thought this would work, but it does not and I'm clearly confused

dash -n flag

Am I crazy or is this a bug in "dash"? The following was found on Ubuntu 10, which uses dash as /bin/sh: % /bin/sh -nvc foobar /bin/sh: foobar: not found According to my understanding of standards, and of every other shell I've seen, the -n flag should prevent the shell from attempting to run "foobar". In fact here's what the dash man page says: -n If not interactive, read commands but do not execute them. This is useful for checking the syntax of shell scripts. This shell is clearly not interactive but proof is given by % /bin/sh -n -c 'echo $-' n So: is this a well k

Which shells have an "unknown hook" (like Tcl)?

Tcl has a feature where if you give it an unknown command, it invokes a procedure which can attempt to resolve the command (perhaps by loading the library that defines that command). I have a situation now where it would be desirable to have that functionality in a "mainstream" shell. I thought that tcsh would have it, but a cursory reading of the man page did not reveal anything. Do any mainstream shells have this capability? -- > No, I haven't, that's why I'm asking questions. If you won't help me, > why don't you just go find your lost manhood elsewhere. CLC in a nutshell.

101 stuff; ( ) and logic; bash

Is this correct? This is what I want if [ ! ( $a == $testing -a ( $b == $c -o $b == $d ) ) ] ; then you have to escape the () ... correct? if [ ! \( $a == $testing -a \( $b == $c -o $b == $d \) \) ] ; then I just had to ask.. it's been a long time. Seems to work but didn't remember ever having to do that. Thanks.

Can you illuminate this dark corner of shell programming? (escaping $ in backquote substitution)

I've been studying portable shell programming for a few months now. I've wrapped my head pretty well around the subject, persistently tracking down the various mysteries I've found along the way, but there is one mystery left which I just have not been able to crack. So I come to you, wizards of comp.unix.shell, in search of enlightenment. When using backquote command substitution, why on Earth does a backslash get annihilated when preceding the $ character? To illustrate what I'm talking about, consider the following sample code: $ cd /tmp $ testvar=3D`echo $PWD` What does

Reformatting an ASCII file

I have an ASCII file with a large number of lines. Each line has the following structure: 1) An alphanumeric string starting at column 0 and up to 20 characters in length. 2) A sequence of 10 space characters starting at the column where the alphanumeric string above ended. 3) An alphanumeric string starting at the column where the sequence of space characters above ended. I want to change this so that the number of space characters between the alphanumeric strings above is variable, in such a way that all the alphanumeric strings mentioned in 3 start exactly at th

ERR trap

Suppose I want to bail out of a script if any command exits with a non-zero status.
