[gmx-users] printf + trjcat

[Hector Martinez-Lopez]

Hey! I'm trying to use


```

printf "c\nc\nc" | trjcat -f 1.trr 2.trr 3.trr -o all.trr -settime

```


without results. I readed in other threads, here at the list, that it can be used as:


```

trjcat -f 1.trr 2.trr 3.trr -o all.trr -settime <<EOF

c

c

c

EOF

```


and it worked for me, also that can be used as


```

trjcat -f 1.trr 2.trr 3.trr -o all.trr -settime < three_c.txt

```


but this didn't worked for me.


So, I'm wondering why we can't use | (pipe) with printf on trjcat, while we can use them with solvate or other tools.


Also, can I fill an issue requesting trjcat to work with printf or to have a variable in which we can dump the letters for the -settime?


Thank you!
