Title: ”Argument list too long“ for decoderawtransaction Post by: mhps on June 24, 2016, 05:47:55 AM hi,
I get an ”Argument list too long“ shell error when running $BITCOIND decoderawtransaction $foo where $foo is a raw tx that is 158kb long from getrawtransaction, on Ubuntu linux. How to get around it w/o recompiling the kernel? Title: Re: ”Argument list too long“ for decoderawtransaction Post by: cr1776 on June 24, 2016, 11:54:02 AM What does
getconf ARG_MAX Show? There may not be another solution except recompiling since I don't think xargs would help here. Title: Re: ”Argument list too long“ for decoderawtransaction Post by: theymos on June 25, 2016, 05:08:55 AM The bottom of help decoderawtransaction shows you how to execute the command using JSON-RPC via curl:
Code: curl --user myusername --data-binary \ You can put the {"jsonrpc":... stuff into a file (omit the single quotes) named for example TEMPFILE and then change the command to: Code: curl --user myusername --data-binary @TEMPFILE -H 'content-type: text/plain;' http://127.0.0.1:8332/ This requires that you set an RPC user and password in your bitcoin.conf. Change "myusername" above to your actual RPC user. Since the data is in a file and never passed through the shell, I think that this should work, though I haven't tested it.

I removed the -H part to get json format output, where the decoded raw tx is in the "result" field. I also changed -data-binary to -data so that it doesn't matter if the hex tx has a \n in it.

Title: Re: ”Argument list too long“ for decoderawtransaction Post by: gmaxwell on August 19, 2018, 05:39:51 PM bitcoin-cli has the -stdin argument for this reason. (both too long inputs and keeping passwords off command lines...)

The insecure way of doing this is: Code: bitcoin-cli walletpassphrase <mysecretpassphrase> <unlock time in seconds> So if you want to unlock your wallet with passphrase "secretenough" for 5 minutes you should do: Code: bitcoin-cli walletpassphrase secretenough 300 However this means your passphrase is also stored in your bash history, something you might not want. As gmaxwell was referring to you can use the -stdin argument if you don't want this to happen. The way this works is: Code: bitcoin-cli -stdin walletpassphrase Code: secretenough Use CTRL-D after supplying all the arguments. This will unlock your wallet without the passphrase getting written to your bash history.
