I am using grep and I want the output to go into two files without going to the screen. I used tee to get the output into two files, but it is also putting the output on the screen which i do not want. Can this be fixed. (2 Replies)
I have access to an AIX 5.3 box, where I need to write a report to:
/tmp/report
The report is larger then the amount of available disk space on the box.
There's about 1 GB of free space, for a 1.5 GB report.
The report is destined for another box (10.0.0.2) anyway, which has enough free... (2 Replies)

I can use pipe output to a file. For example
./somescript.sh > output.txt
But for example if the output from ./somescript.sh is slow. like if it prints one line every minute then output.txt is not updated every minute. Lines are written to output.txt in one go, hence have to wait for the whole... (2 Replies)

xargs work great when a command gives multiple line output which can be input to another. In my case it is not working coz the second command uses two words in it.

another command takes these number as inputs. it works great... (1 Reply)

HASHSTASH(3) libbash hashstash Library Manual HASHSTASH(3)NAME
hashstash -- libbash library that implements hash data structure
SYNOPSIS
hashSet <Value> <Key> <HashName> [SubHashName [...]]
$retval hashGet <Key> <HashName> [SubHashName [...]]
$retval hashKeys <HashName> [SubHashName [...]]
hashRemove <Key> <HashName> [SubHashName [...]]
hashDelete <HashName> [SubHashName [...]]
DESCRIPTION
General
hashstash is a collection of functions that implement basic hash data-structure in bash scripting language.
The function list:
hashSet Adds a value to the hash
hashGet Returns a value from the hash
hashKeys Returns a list of keys of the hash
hashRemove Removes a key from the hash
hashDelete Deletes a hash
Detailed interface description follows.
FUNCTIONS DESCRIPTIONS
hashSet <Value> <Key> <Hashname> [SubHashName [...]]
Adds a value to the hash.
Parameters:
<Value>
The value to set in HashName[Key].
<Key>
The key for the value Value.
<HashName> [SubHashName [...]]
A string that contains the name of the hash. If the hash is a sub hash of another hash, the "father hash" name MUST BE WRITTEN FIRST,
followed by the sub-hash name.
Value will be the value of the key Key in the hash HashName. For example if you have (or want to define) hash C, which is subhash of hash B,
which is subhash of hash A, and C has a key named ckey1 with value cval1, then you should use:
hashSet cval1 ckey1 A B C
$retval hashGet <Key> <HashName> [SubHashName [...]]
Returns the value of Key in HashName to the $retval variable.
Parameters:
<Key>
The key that hold the value we wish to get.
<HashName> [SubHashName [...]]
A string that contains the name of the hash. If the hash is a sub hash of another hash, the "father hash" name MUST BE WRITTEN FIRST,
followed by the sub-hash name.
Return Value:
The value of the key Key in the hash HashName. The value is returned in the variable $retval.
$retval hashKeys <HashName> [SubHashName [...]]
Returns a list of keys of the hash HashName in the variable $retval.
Parameters:
<HashName> [SubHashName [...]]
A string that contains the name of the hash. If the hash is a sub hash of another hash, the "father hash" name MUST BE WRITTEN FIRST,
followed by the sub-hash name.
Return Value:
The value of the key Key in the hash HashName. The value is returned in the variable $retval.
hashRemove <Key> <HashName> [SubHashName [...]]
Removes the key Key from the hash HashName.
<Key>
The key we wish to remove from HashName.
<HashName> [SubHashName [...]]
A string that contains the name of the hash. If the hash is a sub hash of another hash, the "father hash" name MUST BE WRITTEN FIRST,
followed by the sub-hash name.
This function should also be used to remove a sub-hash from its "father hash". In that case, the key will be the name of the sub-hash.
hashDelete <HashName> [SubHashName [...]]
Deletes the hash HashName [SubHashName [...]].
Parameters:
<HashName> [SubHashName [...]]
A string that contains the name of the hash. If the hash is a sub hash of another hash, the "father hash" name MUST BE WRITTEN FIRST,
followed by the sub-hash name.
If this function is used on a sub-hash, a key with the name of the sub-hash will remain in its "father hash" and will hold a NULL value.
BUGS
A hash name can only contain characters that are valid as part of bash variable names (i.e. a-zA-Z0-9_). The same applies for hash keys.
As for now, there is no way of knowing if a key represents a value or a sub-hash. If a sub-hash will be used as a key, the returned value
will be its keys list.
EXAMPLES
Define hash table hashA with key Akey1 with value Aval1 use:
% hashSet Aval1 Akey1 Ahash
Now:
% hashGet Akey1 Ahash
% echo $retval
Aval1
% hashKeys Ahash
% echo $retval
Akey1
%
HISTORY
The idea to write hashstash library appeared when we've discovered the full power of the bash eval function.
As of the name hashstash, it has two meanings. The first, it means 'stash' of hash functions. The second is, that hashstash contains sub-
hashes inside, so it looks like stash of packed information.
