This is a rather roundabout way of sending files! sshpass executing sshpass executing scp. Isn't there a better way?
Anyway, this doesn't do what you think. Each ID only gets used once. The first statement will contain the first and second ID; the second contains the third and fourth. Et cetera.
Hi,
I'm trying to write a function that redirects the contents of an
array to a file. The array contains the lines of a data file with
white space.
The function seems to preserve all white space when redirected
except that it seems to ignore newlines. As a consequence, the
elements of the... (7 Replies)
Hi Guys,
I have a file which has numbers in it separated by newlines as follows:
1.113
1.456
0.556
0.021
-0.541
-0.444
I am using the following code to store these in an array in bash:
FILE14=data.txt
ARRAY14=(`awk '{print}' $FILE14`) (6 Replies)
I have one file "file.a.b.c-d.r" that I would like to use to spawn 4 other files:
"file.a.b.1-A.r"
"file.a.b.1-B.r"
"file.a.b.1-C.r"
"file.a.b.1-D.r"
where the field "c-d" changes into my 1 and A-D.
I was doing this manually at the prompt with

I have figured out how to grep the file like this:
echo `grep $(date +'%Y-%m-%d') Cos-01.csv | cut -d',' -f1`
The above line does echo the correct information from the lines in which my search criteria is found.
Now I am trying to get that information (Yes, just one column of every line) into... (6 Replies)

Hi,
I'm trying to write a bash script that takes a file and passes each line from the file into an array with elements separated by column.
For example:
Sample file "file1.txt":
1 name1 a first
2 name2 b second
3 name3 c third
and have arrays such as:
line1 = ( "1" "name1" "a"... (3 Replies)
for a in {1..100}
do
awk '{ sum+=$a} END {print sum}' a=$a file1 > file2
done
I know I will get only one number if following the code above, how can I get 100 sum numbers in file2? (2 Replies)

xstr
xstr(1) User Commands xstr(1)NAME
xstr - extract strings from C programs to implement shared strings
SYNOPSIS
xstr -c filename [-v] [-l array]
xstr [-l array]
xstr filename [-v] [-l array]
DESCRIPTION
xstr maintains a file called strings into which strings in component parts of a large program are hashed. These strings are replaced with
references to this common area. This serves to implement shared constant strings, which are most useful if they are also read-only.
The command:
example% xstr -c filename
extracts the strings from the C source in name, replacing string references by expressions of the form &xstr[number] for some number. An
appropriate declaration of xstr is prepended to the file. The resulting C text is placed in the file x.c, to then be compiled. The
strings from this file are placed in the strings data base if they are not there already. Repeated strings and strings which are suffixes
of existing strings do not cause changes to the data base.
After all components of a large program have been compiled, a file declaring the common xstr space called xs.c can be created by a command
of the form:
example% xstr
This xs.c file should then be compiled and loaded with the rest of the program. If possible, the array can be made read-only (shared) sav-
ing space and swap overhead.
xstr can also be used on a single file. A command:
example% xstr filename
creates files x.c and xs.c as before, without using or affecting any strings file in the same directory.
It may be useful to run xstr after the C preprocessor if any macro definitions yield strings or if there is conditional code which contains
strings which may not, in fact, be needed. xstr reads from the standard input when the argument `-' is given. An appropriate command
sequence for running xstr after the C preprocessor is:
example% cc -E name.c | xstr -c -
example% cc -c x.c
example% mv x.o name.o
xstr does not touch the file strings unless new items are added; thus make(1S) can avoid remaking xs.o unless truly necessary.
OPTIONS -c filename Take C source text from filename.
-v Verbose: display a progress report indicating where new or duplicate strings were found.
-l array Specify the named array in program references to abstracted strings. The default array name is xstr.
FILES
strings data base of strings
x.c massaged C source
xs.c C source for definition of array "xstr*(rq
/tmp/xs* temp file when xstr filename doesn't touch strings

SEE ALSO make(1S), attributes(5)BUGS
If a string is a suffix of another string in the data base, but the shorter string is seen first by xstr both strings will be placed in the
data base, when just placing the longer one there would do.
NOTES
Be aware that xstr indiscriminately replaces all strings with expressions of the form &xstr[number] regardless of the way the original C
code might have used the string. For example, you will encounter a problem with code that uses sizeof() to determine the length of a lit-
eral string because xstr will replace the literal string with a pointer that most likely will have a different size than the string's. To
circumvent this problem:
o use strlen() instead of sizeof(); note that sizeof() returns the size of the array (including the null byte at the end),
whereas strlen() doesn't count the null byte. The equivalent of sizeof("xxx") really is (strlen("xxx"))+1.
o use #define for operands of sizeof() and use the define'd version. xstr ignores #define statements. Make sure you run xstr on
filename before you run it on the preprocessor.
You will also encounter a problem when declaring an initialized character array of the form
char x[] = "xxx";
xstr will replace xxx with an expression of the form &xstr[number] which will not compile. To circumvent this problem, use static char *x
= "xxx" instead of static char x[] = "xxx".
