Yes, but it would be cumbersome and plain ugly. Writing scripts (i suppose you need it in a script) is all about clarity and making it easy to understand what is done, therefore you should do it in...

You have already shown us that you know how to get what you want:
text="iv-hhz-sac/hpac/hhz.d/iv.hpac..hhz.d.2016.250.070018.sac"
result=${text%.*}
result=${result##*/}
printf '%s\n' "$result"...

Why do you think that is a funny thing??? By definition, a continuation backslash is a <backslash> character IMMEDIATELY followed by a <newline> character. If there is any character between a...

Why not
printf "%02d:%02d:%02d\n" $((25793 / 3600)) $((25793 % 3600 / 60 )) $((25793 % 3600 % 60))

You have started well over 300 threads in the last seven years. You know what is needed for us to be able to help you efficiently:

The white box is probably you input cursor you can hide/view it like this:

# Counts the number of files to process

Your code uses command substitution (i.e., $(command arguments)). That involves forking a shell, executing command, waiting for command to finish, reading the results from command, and assigning...

First, I suggested using find $PWD ...; not find $pwd .... Your shell sets PWD to an absolute pathname of your current working directory when it starts up and updates it every time you successfully...

Have you considered using an absolute pathname on the find (i.e. find "$PWD" ... instead of find . ...) and moving to the directory in which you want the files to be created before invoking mseed2sac...

The command:
i=$((i++))
does the following things, in sequence:

$((i++)) part 1: save the initial value of i,
$((i++)) part 2: increment the value of i,
$((i++)) part 1: return the...

I don't really follow you. Nothing will be lost with 'mkdir', despite your earlier assertion that "I think that `mkdir -p` overwrites the directories. I want to avoid that". mkdir doesn't do anything...

mkdir -p will create intermediary directories only as necessary. That is, it won't try to re-create it if the directory already exists.

Try:
for i in sac_pzs_*
do
mv "$i" "${i#sac_pzs_}.sac.pzs"
done

Can't be done with grep alone; either deploy precursor or trailing commands, or use e.g. awk or sed to start matching at your target line downwards:
sed -n '/@unnumbered References/,$ {/some...

Wouldn't you need to account for the archives being gzipped; either by gunzipping them first or by adding the -z option to tar.

Try something like this?
find "$(pwd)" -type d |
while read dir
do
cd "$dir" || continue
for archive in *.tar.gz
do
if [ -r "./$archive" ]; then
tar zxf "./$archive"
fi
...

Please, follow the first set of instructions if you can now, using chroot. That's a bit safer.
If not, try the last resort option of blowing the password, manually.

Instead of else if, use elif, then it should work, provided you use a lowercase T in then and you use spaces around the square brackets...

How about ls | while read FN; do NE=${FN%.*}; echo mv ${FN} ${NE##*_}_${FN%_*}${FN#${NE}}; done

Some other features to consider:


Enter an initial time for both players.
Count backwards.
Stop both clocks (tournament director resolving problem).
Resume.

Or, to turn that around:

Would you want people to be able to do that to you? Run completely anonymous code which can't be tracked, analyzed, controlled, accounted, reviewed, or trusted in any...

You could also try something like this:

#!/bin/bash

files=$(find . -name "kay.even*.png.pdf")

num=2001
for fl in $files
do
prefix=${fl%%[0-9]*}
suffix=${fl##*[0-9]}
((num+=2))...

The echo commands are not your problem. There is a huge difference between:
test : $(mn)/getvel_main.cpp
$(C++) $(OPT) $(DEF) $(IDIR) $(mn)/getvel_main.cpp -o getvel
-mv getvel ./gbinand:...

It would be safer to use:
awk -v s="/geopdf/" -v d="/" '{gsub(s,d); print}' /home/chrisd/Desktop/geo1937/geo02n01.html
in case other directory names ending in "geopdf" could appear in your data.

itoa is not standard function, this function is not defined in ANSI-C and C++. So it's not supported by some compiler such as g++. better you create your own function to convert int to string and...
