[Bash] passing variables to executable doesn't work
Bash version 4.4.20 / Ubuntu 16.0.4
Hello,
I tried to write a script that gathers some data and passes them to an executable.
The executed application answers with an error. The echo output in the script returns correct values.
If I copy/paste the last echo command, it get's executed correctly.
You can't reproduce the error, maybe you can improve the code that it should work then.
Code:
#!/bin/bash
#creates an array with name gettx
declare -a gettx
#enter your public address from: StealthCoind getaddressesbyaccount ""
pubaddress=mzYfB7ZEurhm8UosBc1a5t4QtRCHjtVw4Z
#enter your pubkey from: StealthCoind getqposinfo
pubkey=0364d6d9039b74c69e2a7dabd81ff27c5cab0b7d54cda0f7419b94e02ff91f9
#Does a transaction and stores the transaction id into the txid variable
txid=$(StealthCoind sendtoaddress $pubaddress 0.01)
#Fill the gettx array with the needed vout number
gettx=($(awk -F: '{split($2,a,","); print a[1]}' <<<"$(StealthCoind gettransaction $txid | sed -n /0.01000000/,/}/p)"))
#Show content of txid for debugging
echo "TXID: $txid"
#show vout number for debugging
echo "vout n: ${gettx[1]}"
#show the build command chain for debugging
echo "StealthCoind claimqposbalance $txid ${gettx[1]} 10"
#execute the command to claim
StealthCoind claimqposbalance $txid ${gettx[1]} 10
without using ls, just using echo so purely pattern matching
I can say echo */ <-- lists directories
but how would I match files? surely something like *!/ or * but neither work ?
it seems like there isn't much that I can put in but surely i should be able to put any ascii... (1 Reply)

Hi,
I'm trying to write a script that checks gvfs to see if a mount exists so I can run it from network-manager's status hooks. I thought I'd pipe the output of gvfs-mount -l to grep for the particular mounts I care about. When I do this in a bash script:

Hi everyone,
I've an issue trying to soustracte two dates, e.g:
d1=$(date -d "Nov 18, 2017" +%s)
d2=$(date +%s) # Today we are 2017-11-16
echo "$(( (d1 - d2) / 86400 ))"
Output:

I don't understand why it doesn't work. for me, it should give "18 - 16 = 2".
Much appreciated... (1 Reply)

commit_prepared
COMMIT PREPARED(7) PostgreSQL 9.2.7 Documentation COMMIT PREPARED(7)NAME
COMMIT_PREPARED - commit a transaction that was earlier prepared for two-phase commit
SYNOPSIS
COMMIT PREPARED transaction_id
DESCRIPTION
COMMIT PREPARED commits a transaction that is in prepared state.
PARAMETERS
transaction_id
The transaction identifier of the transaction that is to be committed.
NOTES
To commit a prepared transaction, you must be either the same user that executed the transaction originally, or a superuser. But you do not
have to be in the same session that executed the transaction.
This command cannot be executed inside a transaction block. The prepared transaction is committed immediately.
All currently available prepared transactions are listed in the pg_prepared_xacts system view.
EXAMPLES
Commit the transaction identified by the transaction identifier foobar:
COMMIT PREPARED 'foobar';
COMPATIBILITY
COMMIT PREPARED is a PostgreSQL extension. It is intended for use by external transaction management systems, some of which are covered by
standards (such as X/Open XA), but the SQL side of those systems is not standardized.
